  • Magnetic removal of cesium ions using γ-poly(glutamic acid)-coated magnetite particles with the enhanced effect of zeolite supplementation, Le Thi Xuan Thuy, Mikito Yasuzawa, Tomoki Yabutani, Bulletin of the Chemical Society of Japan, 86, 958, 962, 2013年08月, 00092673, 10.1246/bcsj.20130020, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84882931888&origin=inward, Magnetic removal of cesium ions (Cs) by γ-poly(glutamic acid)-coated magnetite particles (PGA-MPs) was investigated using a variety of waters. Cs was sufficiently removed from fresh water in a pH range from 7.0 to 9.0, with a removal efficiency of higher than 80% by using 5wt% PGA-MPs, while that from artificial seawater was limited to 30%. Zeolite particles were employed as a supplementary adsorbent to adsorb Cs before the collection of zeolite with PGA-MPs. The addition of 1wt% zeolite particles enhanced the recovery of Cs up to 97.7 ± 0.2% for fresh water and the amount of PGA-MPs required for the treatment was reduced to 0.2 wt%. Nevertheless, such improvement was not observed for artificial seawater treatment. The zeolite supplementation method performed sufficiently on the recovery of Cs in tap water and spring water, and their recoveries were both higher than 93% with R.S.D. of less than 1%. These results strongly suggest that the provided procedure can be practically applied to the removal of Cs from various inland waters.

  • Serum concentration of selenium in diarrheic patients with and without HIV/AIDS in Gondar, Northwest Ethiopia, Bemnet Amare, Ketema Tafess, Fusao Ota, Feleke Moges, Beyene Moges, Berhanu Andualem, Tomoki Yabutani, Afework Kassu, Journal of AIDS and Clinical Research, 2, 2011年12月, 10.4172/2155-6113.1000128, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84874107930&origin=inward, Background: Selenium deficiency is known to be a major public health problem, associated with increased risk of mortality with AIDS and AIDS-related complex, diarrhea included compared to those of healthy controls. In Ethiopia, there are no studies conducted on serum selenium status diarrheic patients with and without HIV infection. Therefore, the present study was aimed at determining the level of serum selenium in HIV infected and sex and aged matched HIV negative diarrheic patients. Methods: This was a cross-sectional study of 206 (97 HIV seronegative and 109 HIV seropositive) diarrheic patients of both genders seen at University of Gondar Hospital, Gondar, Ethiopia. Serum selenium was measured by inductively coupled plasma-mass spectrometer. Results: The mean and standard deviation of serum selenium levels in HIV seropositives was 5.90 ± 2.78 μg/dl and in HIV seronegatives was 6.99 ± 4.26 μg/dl. Deficiency of selenium was seen in 95.9% and 71.56% of diarrheic patients with and without HIV co-infection, respectively. The over all selenium deficiency was observed in 83.0% of patients included in the study irrespective of their HIV serostatus while 85.3%of the patients infected with HIV and 80.4% of patients without HIV infection had serum selenium level below 7μg/dl. The low serum selenium level was not associated with presence or absence of intestinal parasites neither with sociodemographic variables such as age, residence, marital status, occupation, monthly income. The mean serum selenium level of all male cases was statistically significantly lower than that of the females (P<0.05). Conclusion: Our results show high prevalence of selenium deficiencies in HIV seropositive and seronegative diarrheic patients in Gondar, Ethiopia. Although this is a small group of study subjects, the findings may be used as a tool to suggest further in-depth prospective clinical trials to determine whether selenium supplements may be of public health benefit among HIV-infected populations as a stand-alone therapeutic approach and potentially as an adjuvant to antiretroviral therapy. © 2011 Amare, et al.
  • Selectivity and regeneratability evaluation of antigen analogous-modified surface film for polychlorinated dibenzodioxin immunosensor using surface plasmon resonance measurement, Mikito Yasuzawa, Norimichi Futagami, Yusuke Fuchiwaki, Tomoki Yabutani, Junko Motonaka, Bunseki Kagaku, 60, 81, 86, 2011年02月, 05251931, 10.2116/bunsekikagaku.60.81, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=79951900164&origin=inward, For the development of a sensitive and accurate immunosensor, the production of a highly specific surface to the corresponding antibody is essential. Moreover, a specific surface having good reusability is worthwhile for constructing a prompt auto-monitoring immunosensing system. In this study, antigen analogous-modified gold substrates having a specific adsorption property to an anti-dioxin antibody, were prepared by the immobilization of 2,4,5-trichlorophenoxy (TCP) derivatives on a gold surface using various methods. An anti-dioxin antibody, which has a good correlation immunoaffinity with the total toxic equivalent quantity (TEQ) of polychlorinated dibenzo-p-dioxins, was employed as a specific antibody, and the specification of the surface was evaluated by a comparison of the surface plasmon resonance (SPR) responses to a specific anti-dioxin antibody and non-specific anti-hemoglobin antibody. In order to obtain a firm and stable immobilization of TCP, a carboxyl group was introduced on gold by a self-assemble monolayer (SAM) technique, and TCP derivatives were attached to the SAM surface with covalent bonding directly and indirectly through the presence of a hexamethylene chain, bovine serum albumin (BSA), and ethylene glycol oligomer (EGO). A TCP derivative-immobilized substrate, prepared using BSA, showed poor reusability. A TCP derivative-immobilized substrate having EGO was highly specific to an anti-dioxin antibody, while that prepared by the direct immobilization of TCP and with introduction of a hexamethylene chain presented nonspecific adsorption. In addition, a TCP derivative-immobilized substrate having EGO showed a good reproducible response from the second repetition, and was reusable more than seven times. © 2011 The Japan Society for Analytical Chemistry.
  • Flow-injection amperometric determination of urine glucose using platinum electrode modified with nafion® and saccharide substitued polypyrrole, Mikito Yasuzawa, Makoto Kitahara, Tomoki Yabutani, Junko Motonaka, Bunseki Kagaku, 58, 941, 944, 2009年12月, 05251931, 10.2116/bunsekikagaku.58.941, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=77950610196&origin=inward, A flow-injection amperometric analysis system for the determination of glucose in human urine was analyzed. The glucose sample was mixed with glucose oxidase, and was introduced into the flow-injection system. Hydrogen peroxide produced by an enzymatic reaction was amperometrically detected by a platinum electrode modified with Nafion, and an electrochemically polymerized saccharide substituted polypyrrole. The influence of electroactive compounds such as ascorbic acid, uric acid, and acetaminophen to the glucose response observed in this system was negligible. A good linear relationship between the glucose concentration and the response current was obtained within a concentration of up to 22.4 mmol dm-3. The relative standard deviation for ten replicate analyses of 5.6 mmol dm-3 glucose in human urine was 7.4%. © 2009 The Japan Society for Analytical Chemistry.
  • Multielemental determination of trace elements in sewage sludge by inductively coupled plasma mass spectrometry and inductively coupled plasma atomic emission spectrometry, Shinsuke Akatsuki, Ryoji Yamanouchi, Yumi Nakamoto, Koji Yoshizumi, Mitsuharu Ogaki, Tomoki Yabutani, Yukako Hayashi, Junko Motonaka, Bunseki Kagaku, 57, 659, 666, 2008年11月, 05251931, 10.2116/bunsekikagaku.57.659, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=55949091783&origin=inward, A multielemental determination method for major-to-trace elements in sewage sludge has been developed by inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) after microwave radiation assisted acid digestion or alkali fusion. A reference material of sewage sludge (BCR-144R) was analyzed to verify the determination method. The determined values of some elements such as Zn, Cu, Pb, Ni, Co and Cd by the alkali fusion were lower than the certified values. The analytical values of Cu and Ni obtained by the alkali fusion method with a platinum crucible was lower than those with a pyrolysis boron nitride crucible. From these results, it was suggested that the losses in the alkali fusion were due to volatilization among ignition for Zn, Pb, Co and Cd and alloy formation between Cu and Ni and platinum as crucible material. Furthermore, hydrofluoric acid was necessary to dissolve niobium, tantalum and hafnium in both decomposition processes for acid digestion and alkali fusion. The microwave radiation assisted acid digestion/ICP-MS and ICPAES method was applied to the determination of major-to-trace elements in a sewage sludge sample collected at a sewage treatment plant in Tokushima. As a result, 44 elements could be determined. © 2008 The Japan Society for Analytical Chemistry.
  • Serum zinc, copper, selenium, calcium, and magnesium levels in pregnant and non-pregnant women in Gondar, Northwest Ethiopia, Afework Kassu, Tomoki Yabutani, Andargachew Mulu, Belay Tessema, Fusao Ota, Biological Trace Element Research, 122, 97, 106, 2008年05月, 01634984, 10.1007/s12011-007-8067-6, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=47049122291&origin=inward, Pregnant women in developing countries are vulnerable to multiple micronutrient deficiencies. Studies assessing serum levels of the micronutrients and magnitude of their deficiencies are very scarce in African subjects. This study was aimed at determining serum levels of micronutrients in 375 pregnant (42 HIV seropositive) and 76 non-pregnant women (20 HIV seropositive) who visited the University of Gondar Hospital, Gondar, Ethiopia. Serum concentrations of zinc,\ copper, selenium, calcium, and magnesium were determined using an inductively coupled plasma mass spectrometer. Irrespective of HIV serostatus, pregnant women had significantly higher serum concentrations of copper and copper/zinc ratio and significantly lower magnesium compared to those in non-pregnant women (P∈<∈0.05). Except for selenium, which was significantly lower in HIV-seropositive pregnant women (P∈<∈0. 05), the mean serum concentrations of zinc, copper, calcium, and magnesium were not significantly different between pregnant women by HIV serostatus. The prevalence of deficiency in zinc, magnesium, selenium, and calcium in the pregnant women, irrespective of their HIV serostatus, was 66.7%, 25.6%, 21.9%, and 9.3%, respectively. The magnitude of deficiency in zinc, magnesium, and selenium was significantly higher in HIV seropositive pregnant women (76.2%, 52.4%, and 45.2%) than that in HIV-seronegative pregnant women (65.5%, 22.2%, and 18.9%) and in HIV-seronegative non-pregnant women (42.9%, 8.1%, and 30.4%; P∈<∈0.05). Deficiency in one, two, three, or four mineral elements was observed in 44.8%, 14.4%, 9.9%, and 5.1% of the pregnant women, respectively. Only 25.9% of the pregnant women and 44.7% of the non-pregnant women were not deficient in any of the micronutrients. The high prevalence of micronutrient deficiencies in pregnant and non-pregnant women in Gondar, Ethiopia warrants the need for strategies on prevention and control of the deficiencies. © 2007 Humana Press Inc.
  • Micronutrient deficiencies and anemia among preschool children in rural Vietnam, Nguyen Van Nhien, Nguyen Cong Khan, Nguyen Xuan Ninh, Phan Van Huan, Le Thi Hop, Nguyen Thi Lam, Fusao Ota, Tomoki Yabutani, Vu Quynh Hoa, Junko Motonaka, Takeshi Nishikawa, Yutaka Nakaya, Asia Pacific Journal of Clinical Nutrition, 17, 48, 55, 2008年03月, 09647058, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=51649089151&origin=inward, The prevalence of trace elements deficiencies, vitamin A deficiency, anemia, and their relationships were investigated in a cross sectional study involving 243 children aged from 12 to 72 months in rural Vietnam. Serum levels of copper, zinc, selenium and magnesium were determined by inductively coupled plasma mass spectrometer and that of retinol by high performance liquid chromatography. Hemoglobin concentration in whole blood was measured by the cyanmethemoglobin method. The prevalence of deficiencies in zinc, selenium, magnesium, and copper was 86.9%, 62.3%, 51.9%, and 1.7%, respectively. On the other hand, 55.6% were anemic and 11.3% had vitamin A deficiency. Deficiency in two or more micronutrient was found in 79.4% of the children. Parameters associated significantly with anemia were selenium deficiency (OR 2.80 95% CI 1.63-4.80, p = 0.0002) and serum retinol <1.05 μmol/L (OR 1.83, 95% CI 1.10-3.05, p = 0.021). Magnesium deficiency (OR 3.09 95% CI 1.36-7.03) was found to be a risk factor for zinc deficiency and vice versa. The results indicate that micronutrient deficiencies are prevalent among preschool children in Vietnam. In addition, the results also demonstrate a strong relationship between selenium deficiency and anemia. Clearly, sustainable strategies are urgently required to overcome the problems in the country.
  • Simultaneous determination of trimethyl- and triethyllead in urban dust by species-specific isotope dilution/gas chromatography-inductively coupled plasma mass spectrometry, Tomoki Yabutani, Junko Motonaka, Kazumi Inagaki, Akiko Takatsu, Takashi Yarita, Koichi Chiba, Analytical Sciences, 24, 791, 794, 2008年01月, 09106340, 10.2116/analsci.24.791, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=49749149176&origin=inward, Both 206 Pb-labeled trimethyllead (TML) and triethyllead (TEL) were synthesized from 206 Pb-enriched metallic Pb certified reference material (NIST SRM 983) and iodomethane or iodoethane through a one-process reaction in a closed system using centrifuge tubes, respectively. Organolead compounds in an urban dust reference material (BCR CRM 605) were extracted with an acetic acid/methanol (1:1) solution, which was mechanically shaken for 24 h. After adjusting the pH of the extracted solution to pH 5, the extracted organolead compounds were derivatized by tetrabutylammonium tetrabutylborate (TATB) and measured with GC-ICPMS. The analytical results of TML and TEL for BCR CRM 605 were 8.22 ± 0.04 mg kg -1 (mean ± standard deviation, n = 3) and 1.12 ± 0.06 mg kg -1 , respectively. The analytical results of TML agreed well with the certified value (7.9 ± 1.2 mg kg -1 ). 2008 © The Japan Society for Analytical Chemistry.
  • Study of environmental impact by coal-fired power station, Koji Yoshizumi, Mituharu Ogaki, Junko Motonaka, Tomoki Yabutani, International Journal of Modern Physics B, 20, 3884, 3889, 2006年10月, 02179792, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=33751264937&origin=inward, The Tachibana-wan coal-fired power station was constructed on land that was reclaimed using the soil that came from cutting through half of a small island while balancing the amount of soil. The power station has been generating for three years. When the electric utility provider projected the power station, it must have conducted an environmental impact assessment, and studied the environmental preservation measures. Moreover, after the power generation began, an environmental investigation was done as a follow up survey to study the environmental impact by the power station based on its construction and use. To study the environmental impact with smoke, the environmental density of sulfur dioxide around the power station was investigated. It fell below the environmental standards at all the environmental measurement points during this investigation. Moreover, a big difference was not seen before and after the beginning of the power generation and the change in these data was in the normal range. As a result of the environmental impact assessment, the contribution density of the power station was near the quantitative limit and a low value. To study the environmental impact with warm wastewater, the water temperature in the bay was investigated. A big difference was not generally seen before and after the beginning of the power generation though the water temperature slowly rose at the discharge point of the warm wastewater but the change of these data was in the normal range. As for the environmental impact, a clear judgment was difficult only from the environmental investigation. It is necessary to set a new environmental indicator to judge the environmental impact. Moreover, as for a new environmental assessment system, it is necessary to introduce a strategic environmental assessment. © World Scientific Publishing Company.
  • Studies on the environmental improvement in Romania, Mitsuharu Ogak, Koji Yoshizumi, Junko Motonaka, Tomoki Yabutani, Yumi Nakamoto, Rodica Stanescu, Marinela Plesca, International Journal of Modern Physics B, 20, 4243, 4248, 2006年10月, 02179792, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=33751267968&origin=inward, In Romania, the communist planned economy system was in place for 42 years but ended due to a revolution in 1989. An environmental administration was started 1990. In order to assist with environment related activities, one of the authors worked in Bucharest for two years from March 2002 to March 2004 as a JICA (Japan International Cooperation Activity) member. One of the most important problems regarding environmental protection in Romania is waste management. In Japan, the regulations and penalties system of waste management have been used for a long time. However, there are many serious problems with the system, such as a decrease in waste disposal facilities and illegally disposed waste. The authors studied a new plan that uses a certification system in order to promote recycling industries. This system is both efficient and inexpensive so it is possible that this method of waste management could be transmitted to Romania. © World Scientific Publishing Company.
  • A long pathlength spectrophotometric tegafur detector using a liquid-core waveguide, Shuji Wada, Tomoki Kawatsu, Yuya Hashizume, Tomoki Yabutani, Junko Motonaka, International Journal of Modern Physics B, 20, 4046, 4050, 2006年10月, 02179792, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=33751284537&origin=inward, A Liquid-Core Waveguide (LCW) detection system for high sensitive determination of tegaful (FT) was developed. In this system the LCW cell was connected to the end of a hollow cathode lump and the other end to a UV spectrometer. A sample solution containing FT was pumped to the LCW cell through a T-shaped connector. A UV absorption of analyte was detected by the UV spectrometer. The configuration of connectors of LCW cell to the light source and the UV detector was designed. Stable and high responses of FT were obtained in a double tube system in which an edge of LCW cell was covered with another tube with large diameter was set in the T-connector. It was found that the UV absorption response of FT obtained in this LCW system depends on the core length and the concentration of FT. The sensitivity of FT obtained by using 65 cm of the LCW cell length was 10-fold higher than that of using 1 cm cell which was often used with a conventional UV-visible detector. © World Scientific Publishing Company.
  • Electrochemical evaluation of the polymer modified micro-electrode for metal ions, Junko Motonaka, Tomoki Yabutani, Keiji Minagawa, Yuji Mishima, International Journal of Modern Physics B, 20, 4057, 4062, 2006年10月, 02179792, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=33751284998&origin=inward, A porous micro-electrode with immobilized poly(methacryroyl alanine) (PMA) was developed for measuring copper(II) ion (Cu 2+) and cadmium(II) ion(Cd 2+). A porous carbon material was packed into the tip of the platinum micro-electrode with a cavity at the top. The porous micro-electrode was dipped in the coating dimethyl sulfoxide solution with PMA and di-2-ethylhexyl phthalate and dried overnight at room temperature. The immobilized PMA on the porous micro-electrode had predominantly a keto form in the buffer solution. In the enol form a metal complex can be formed under the simultaneous liberation of a proton. Calibration curves for measurements of Cu 2+ and Cd 2+, the effects of preconcentration condition, scan rate, pH, and temperature, and lifetime of the PMA modified micro-electrode were examined. Under optimal conditions, the responses of sensor were linear in the concentration range 0.0001-1 mmol l -1 for Cu 2+ and 0.01-1 mmol l -1 for Cd 2+. Analytical values determined with the modified electrode were constant for at least 3 month. © World Scientific Publishing Company.
  • Recovery and extraction of heavy metal ions using ionic liquid as green solvent, Masami Kumano, Tomoki Yabutani, Junko Motonaka, Yuji Mishima, International Journal of Modern Physics B, 20, 4051, 4056, 2006年10月, 02179792, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=33751304690&origin=inward, Ionic liquids are expected to replace conventional organic solvents in organic synthesis, solvent extraction and electrochemistry due to their unique characters such as low volatility, high stability and so on. In this work, N,N,-diethyl-N-methyl-N-(2-methoxyethyl) ammonium bis(trifluoromethansulfonyl) imide was used as an alternative solvent to extract heavy metal ions. As the extracting conditions, the additional effect of 8-hydroxyquinoline (8-HQ) as metal chelating agent into ionic liquids, shaking time and volume ratio were investigated. As extraction efficiency depended on 8-HQ concentration significantly, in order to extract high concentrated metal ions the solubility of 8-HQ into ionic liquid was tested. N,N,-diethyl-N-methyl-N-(2-methoxyethyl) ammonium bis(trifluoromethansulfonyl)imide had good solubility of 8-HQ. Consequently, 5 μmol of copper, zinc, cadmium and manganese could be completely recovered with 100 μl ionic liquid. © World Scientific Publishing Company.

Blood was collected from adult Vietnamese living in the midland of northern Vietnam. One hundred twenty-three subjects in the age range 20-60 yr were included in the study. Anemia, where the concentration of hemoglobin in whole blood is less than 120 g/L in females and 130 g/L in males, was found in 30% (37/123) of the study population. The levels of vitamin Aand selenium in the sera of anemic subjects (n ≤ 37) were significantly lower than that in nonanemic group (n ≤ 86). On the other hand, no significant differences were observed in the concentrations of copper and zinc between the two groups. This study was the first to show serum levels of trace elements in adult Vietnamese, providing useful baseline information for further studies. © Copyright 2006 by Humana Press Inc.

Subjects: A total of 155 TB patients, 74 of which were coinfected with HIV, and 31 healthy controls from Gondar, Ethiopia. Methods: Serum levels of copper, zinc, selenium and iron were determined using an inductively coupled plasma mass spectrometer from all subjects at baseline and from 44 TB patients (22 with HIV coinfection) at the end of an intensive phase of anti-TB chemotherapy. Results: Compared with the control group, the concentrations of iron, zinc and selenium were significantly lower (P<0.05) while that of copper and copper/zinc ratio was significantly higher (P<0.05) in the serum of TB patients. TB patients with HIV coinfection had significantly lower serum zinc and selenium concentrations and significantly higher copper/zinc ratio compared to that in TB patients without HIV coinfection (P<0.05). The serum concentration of zinc had significantly increased at the end of intensive phase of anti-TB chemotherapy in patients without HIV coinfection (P<0.05). An increase in serum selenium level was observed in TB patients with or without HIV coinfection after therapy. On the contrary, serum copper concentration and copper/zinc ratio declined significantly after anti-TB chemotherapy irrespective of HIV serostatus (P<0.05). Conclusions: The results indicate that TB patients have altered profile of trace elements in their sera. This warrants the need for further investigations so that strategies for trace elements supplementation can be planned in addition to their potential as diagnostic parameters in monitoring responses to anti-TB chemotherapy. © 2006 Nature Publishing Group.

  • A multielement masking method using magnesium hydroxide coprecipitation for the selective determination of lead in water samples by differential pulse anodic stripping voltammetry, Tomoki Yabutani, Yasuhiro Utsunomiya, Yukiko Kado, Yuji Tani, Hideyuki Kishimoto, Akinori Fukuda, Junko Motonaka, Analytical Sciences, 22, 1021, 1024, 2006年01月, 09106340, 10.2116/analsci.22.1021, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=33746026681&origin=inward, We present a new multielement masking method using magnesium hydroxide coprecipitation for the selective determination of Pb by differential pulse anodic stripping voltammetry (DPASV). The recovery of Pb in the masking method was over 95%, while interfering ions (Cd 2+ , Co 2+ , Cu 2+ , Fe 2+ , Mn 2+ , and Ni 2+ ) could be removed at 100% from the analytical sample. A linear regression was obtained in the Pb concentration from 10 to 1000 μg kg -1 in the existence of 100 μg kg -1 of the interfering ions. When this method was applied to the determination of Pb in a natural water-standard reference material (NIST 1640), the determined value for Pb in this work (25.4 ± 4.1 μg kg -1 ) almost agreed with the certified value (27.89 ± 0.14 μg kg -1 ). 2006 © The Japan Society for Analytical Chemistry.
  • Removal of phosphate in water to layered double hydroxide, Ryousuke Nomura, Takahiro Mori, Eiji Kanezaki, Tomoki Yabutani, International Journal of Modern Physics B, 17, 1458, 1463, 2003年04月, 02179792, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=0038101456&origin=inward, Layered double hydroxide (LDH) has been used to remove phosphate ion in water as an effective adsorbent of this anion at low concentration. LDH which contains Mg 2+ and Al 3+ as divalent and trivalent metals respectively was prepared as has been published by many authors. A fixed portion of this LDH was suspended in the weakly basic solution containing phosphate. The suspension was stirred moderately followed by filtration. The concentration of phosphate ion in the filtrate was determined by the molybdenum blue method. The result indicates that the LDH used in this experiment was effective in removing phosphate from water. Furthermore, it was also certified that the phosphate anions removed from water were quantitatively transferred onto the solid of LDH.
  • Electrochemical properties of a thiol monolayers coated gold electrode modified with osmium gel membrane as enzyme sensor, Tomoki Yabutani, Nobuyuki Okada, Kenichi Maruyama, Junko Motonaka, International Journal of Modern Physics B, 17, 1193, 1198, 2003年04月, 02179792, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=0038440608&origin=inward, The electrochemical behavior of an enzyme sensor for glucose using a gold electrode modified with thiol self-assembled membrane and osmium complex gel as an electron transferring mediator has further been investigated by electrochemical analysis. The gold electrode was initially coated with aminomethanethiol self assembling mono layer membrane(thiol-SAM) and then immobilized with glucose oxidase using poly(vinylpyridine-co-allylamine) (PVP-co-AA), gel coordinated with osmium bipyridine complexes (GOD/Os-PVP-co-AA gel). The cleaning condition of the surface of the Au electrode prior to coating thiol SAM was optimized for reduction of interference caused by concomitant compounds. It was found that interfering influence was most efficiently reduced in the case of use of the Au electrode immersed into nitric acid. The current ratio with a thiol coated gold electrode modified with Os-PVP-co-AA gel in glucose solution in the presence to absence of ascorbic acid, acetaminophen, and uric acid (ID+1/II) was 1.006, 1.014, and 1.018, respectively. The peak current response of glucose in the electrode modified with thiol SAM was dropped to 60-98% as compared with that without thiol SAM.
  • Preparation and properties of a glucose biosensor based on an osmium-complex modified polypyrrole, Junko Motonaka, Tomoki Yabutani, Kenichi Maruyama, Tokuo Shiomi, Norio Tateishi, Yuji Mishima, Bunseki Kagaku, 51, 1165, 1170, 2002年01月, 05251931, 10.2116/bunsekikagaku.51.1165, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=0036925091&origin=inward, A novel glucose sensor base on an osmium-complex modified polypyrrole was prepared and evaluated. Four new-type osmium-complexes ([Os(bpy) 2(py(4)-bpy)]2+/3+, [Os(bpy)2(py(3)-bpy)] 2+/3+, [Os(bpy)2(pyro-pri)Cl]+/2+, and [Os(bpy)2(vi-bpy)]2+/3+) were synthesized, and the kinetic parameters analyzed. A hydrophilic redox polymer with an osmium-complex was modified by electrolytic copolymerization on the surface of a platinum electrode. The effects of the polymer concentration, times of the scan, dissolved oxygen, and concomitant compounds, and a calibration curve for measurements of glucose were analyzed. The catalytic currents of synthesized osmium-complexes were observed. The relationship between glucose and the oxidation current was examined using the sensor under the optimum conditions. A linear relationship was obtained over the range of 0.9-100 mmol dm-3 glucose. It was measured in the presence of ascorbic acid or uric acid. These compounds did not affect the response current. The lifetime of the sensor was also examined. The analytical values were constant for 9 days when the sensor was stored in a pH 7.07 phosphate buffer solution at 4°C.
  • Fractional distributions of major-to-ultratrace elements in coastal seawater and their partitionings in laboratory-made salts as investigated by inductively coupled plasma atomic emission spectrometry and inductively coupled plasma mass spectrometry with , Shan Ji, Tomoki Yabutani, Akihide Itoh, Hiroki Haraguchi, Bulletin of the Chemical Society of Japan, 73, 1179, 1186, 2000年05月, 00092673, 10.1246/bcsj.73.1179, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=0034046529&origin=inward, The coastal seawater sample was filtered with a membrane filter (pore size 0.45 μm), and the filtrate was further filtered with an ultrafiltration filter (molecular weight permeation limit of 10000 Da). Then, major-to- ultratrace elements in the particles which remained on the membrane filter, the membrane-filtered seawater, and the ultrafiltered seawater were determined by ICP-AES (inductively coupled plasma atomic emission spectrometry) and ICP-MS (inductively coupled plasma mass spectrometry). From these analytical results, the fractional distributions of each element in the particle, large molecule and small molecule fractions of seawater were estimated, where the distributions of the elements in the large molecule fraction were obtained as the differences between the elemental concentrations in membrane-filtered and ultrafiltered seawaters. Furthermore, laboratory-made salts (Salts I-III) were prepared from original, membrane- filtered, and ultrafiltered seawaters. The concentrations of major-to- ultratrace elements in laboratory-made salts were also determined by ICP-AES and ICP-MS. It was found that alkali metals, alkaline earth metals, oxoanion- forming elements (V, Mo, W, U) and Cd were mostly contained in the small molecule fraction of seawater, and ca. 95-100% of them in salt, except for V, originated from those in the small molecule fraction. More than 50% of Al, Mn, Fe, Co, Ga, Y, rare earth elements (REEs) and Pb were contained as the particle constituents in seawater, but their intakes into salt were less than 50%. In addition, the fractional distributions of the following elements in the large molecule fraction of seawater were: Al 10%, Mn 4%, Fe 2%, Cu 23%, Zn 7%, Y 5%, REEs 3-15%, and Pb 30%. On the other hand, the intake factors of these elements in salt from the large molecule fraction were: Al 40%, Mn 5%, Fe 28%, Cu 20%, Zn 30%, Y 7%, REEs 5-30%, and Pb 55%. The results obtained in the present experiment suggest that the distributions of the elements in natural salt greatly depend on the chemical forms in seawater.
  • Simultaneous multielement determination of hydride- and oxoanion-forming elements in seawater by inductively coupled plasma mass spectrometry after lanthanum coprecipitation, Tomoki Yabutani, Shan Ji, Fumihiko Mouri, Akihide Itoh, Koichi Chiba, Hiroki Haraguchi, Bulletin of the Chemical Society of Japan, 73, 4, 895, 901, 2000年04月, 00092673, 10.1246/bcsj.73.895, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=0034094764&origin=inward, The simultaneous multielement determination of trace elements in seawater, especially hydride- and oxoanion-forming elements, has been investigated by inductively coupled plasma mass spectrometry with the aid of lanthanum coprecipitation preconcentration. The optimum pH in lanthanum coprecipitation was pH 9.5; at this value, trace elements were well recovered and major constituents of seawater such as Na, Mg, K, and Ca were significantly reduced in the concentrated solutions. The recovery values obtained for V, Cr(III), Mn, As(III), As(V), Se(IV), Y, Sn, Sb(III), Sb(V), W, Bi, and U were more than 85% after lanthanum coprecipitation, while Cr(VI), Se(VI), and Mo(VI) provided poor recoveries of less than 30%. The reproducibility for coprecipitation was within 5% as relative standard deviation. The present method was applied to the determination of trace elements in coastal seawater reference material CASS-3. The analytical values for Mn, As, V, Y, Sb, W, and U were in fairly good agreement with the certified or literature values.
  • Multielement determination of trace elements in coastal seawater by inductively coupled plasma mass spectrometry with aid of chelating resin preconcentration, Tomoki Yabutani, Shan Ji, Fumihiko Mouri, Hideyuki Sawatari, Akihide Itoh, Koichi Chiba, Hiroki Haraguchi, Bulletin of the Chemical Society of Japan, 72, 10, 2253, 2260, 1999年10月, 00092673, 10.1246/bcsj.72.2253, https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=0032751036&origin=inward, The multielement determination of trace elements in coastal seawater by inductively coupled plasma mass spectrometry has been investigated with the aid of chelating resin preconcentration. First, each coastal seawater sample (250 ml) was treated with a chelating resin (Chelex 100) at pH 6 for preconcentration of trace elements. After filtration with a glass filter, the resin on the filter was carefully rinsed with 8 ml of 1 M ammonium acetate solution. Then, trace elements adsorbed on the resin were eluted with 6 ml of 2 M HNO 3 . As a result, the preconcentration factor of 41.7 fold was obtained, with the total concentration of matrix elements (Na, K, Mg, and Ca) less than 200 mg dm -3 . The recovery values were larger than 80% for 22 elements among 29 elements determined. The present method was applied to the determination of trace elements in the coastal seawater certified reference material CASS-3, issued from National Research Council of Canada (NRC), as well as to the coastal seawater sample collected from Tokoname off-shore.
