Fourest, A. Maslennikov, F. David, M. Masson] A method for simultaneous quantitative determination of Mo(VI), Re(VII), Ru(III) and NO3- ions in aqueous solutions, using capillary zone electrophoresis (CZE) technique with direct UV detection, was developed. Electrophoretic mobility of Ru(III) ions in 0.1M NaHCO3 solution was determined as 6.0×10-8m2 V-1 s-1 at 25 °C. The best analytical characteristics of the developed method were achieved with a 100mM carbonate buffer solution containing 0.3mM TTAB, at a pH value of 9.8 and at an applied voltage of 10kV. Under these conditions, a linear relationship between the measured absorbance (λ=230nm) and the concentration of the species under study were observed in the range 5×10-6-10-3M for Mo(VI), 7×10-6-10-3M for Re(VII) and 10-5--4M for Ru(III). The minimum detectable concentrations were determined as 4.1×10-6M for NO3-, 5.2×10-6M for Mo(VI), 7.4×10-6M for Re(VII) and 1.0×10-5M for Ru(III). The accuracy of quantitative determination was estimated as 3%-5% for NO3- and 5%-6% for Mo(VI), Re(VII) and Ru(III) ions. The presence of 0.06M NaNO3 (HNO3) and of 10-3M U(VI) in the sample affected neither the detection limits of the species under study nor the selectivity of the method. © 2003 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Fourest B. aut Maslennikov A. aut David F. aut Masson M. aut Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 91/8/2003(2003-08-01), 479-486 0033-8230 91:8/2003<479 2003 91 ract https://doi.org/10.1524/ract.91.8.479.20003 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/ract.91.8.479.20003 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Fourest B. aut NATIONALLICENCE 700 1- Maslennikov A. aut NATIONALLICENCE 700 1- David F. aut NATIONALLICENCE 700 1- Masson M. aut NATIONALLICENCE 773 0- Radiochimica Acta/International journal for chemical aspects of nuclear science and technology Oldenbourg Wissenschaftsverlag GmbH 91/8/2003(2003-08-01), 479-486 0033-8230 91:8/2003<479 2003 91 ract CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
