Ion-chromatography of inorganic selenium species with a preliminary preconcentration step

Ion-chromatography of inorganic selenium species with a preliminary preconcentration step

Chromatographia 57(Suppl.): S67-S71

The essential as well as toxic character of selenium is related to its chemical forms and oxidation states. This study presents a method for the determination of Se(IV) and Se(VI) in aqueous solution by ion chromatography with UV detection. Several chromatographic parameters, including mobile phase concentration, pH and methanol content were optimized. The influence of other anions commonly present in water samples was also tested.
