Speciation of Selenium(IV) and Selenium(VI) using Coupled Ion Chromatography—Hydride Generation Atomic Absorption Spectrometry

A simple method was developed to speciate inorganic Se in the mg L range using coupled ion chromatography-hydride generation atomic absorption spectrometry. Because of the differences in toxicity and adsorption behavior, determination of the redox states selenite, Se(IV), and selenate, Se(VI), is important. We used anion exchange chromatography to separate Se(IV) and Se(VI) based on differences...

A Facile Catalytic- Kinetic Method for The Determination of Selenium (IV)

A catalytic-kinetic method for the determination of selenium is proposed. Alizarin navy blue is reduced by sodium sulfide to from a colorless product. The reaction is accelerated by trace amounts of Se (IV), and can be followed by measuring the decrease in absorbance of the dye at 620nm and 30 °C by the fixed time method. Selenium can be determined in the range of 0.004 — 0.12 1.1g.m1-1 . ...

Sn(IV) Compounds Interaction with Metal-Schiff Base Complexes

The formation constants and Gibbs free energy for the interaction of RnSnClm (n = m = 2, R = Me, Ph, n-Bu or n = 4, m = 0, R = Ph) compounds as acceptors, with ML complexes (H2L = N,N'-bis(salicylidene)-2-aminobenzylamine (salabza-H2) and its derivatives, M = Mn2+ or Zn2+), as donors in N,N'-dimethylformamide (DMF) as solvent were studied. These parameters were measured by using UV-vis spectrop...
