Abstract
The voltammetry behavior of iodine and selenium has been studied on new organo-modified electrodes. The conditions have been proposed for the measurement of the analytical signals of iodide and selenium ions on a silver electrode modified by aryl diazonium tosylates containing an amino group in the presence of a 0.1 M solution of N2H4 · H 2SO4 (pH 2-3) without oxygen removal. A new approach and a procedure have been developed for the simultaneous determination of iodine and selenium in tap, drinking, and mineral waters using the organo-modified electrode. The analytical range is from 0.003 to 1.5 mg/L for iodide ions and from 0.003 to 2.0 mg/L for selenite ions.
