INVERSION-CHRONOPOTENTIOMETRIC METHOD FOR THE DETERMINATION OF ARSENIUM (III) IN AQUOEUS SOLUTIONS

摘要

A method for inversion-chronopotentiometric determination of arsenium (III) in aqueous solutions includes measurement on solid gold electrode at positive potential with respect to silver-chloride electrode. The measurement is carried out in inversion-chronopotentiometric way in samples after mineralization of organic substances on solid gold electrode with use of base electrolyte HCl, NaEDTA and copper (II) ions at given electrochemical parameters of collection and inversion of arsenium.
