Abstract

A simple voltammetric method for quantitative determination of total selenium in various waters in the concentration range of 0.003-0.05 mg/liter is described; the method involves a photochemical sample preparation and allows measurements to be carried out with a rated accuracy of 45 rel.%. A distinctive feature of the method is the use of a gold-graphite electrode rather than a mercury electrode and the elimination of interfering anions (chloride, bromide, iodide, nitrate, and others) by replacing the supporting electrolyte at the stage of anodic dissolution of the selenium concentrate. Metrological certification of the method is carried out using the analysis results for waters of 16 types (potable, mineral, river, underground waters, and treated water effluents).
