Determination of selenium speciation in river waters by adsorption on iron(III)-Chelex-100 resin and differential pulse cathodic stripping voltammetry

This paper describes the preconcentration of Se(IV) from polluted waters by iron(III)-loaded Chelex-100 resin and its determination by differential pulse cathodic stripping voltammetry. The method is used to study selenium speciation in waters, and a speciation method, suitable for concentration lev...
