Procedures involving reduction with thiourea. Rapid potentiometric method for determination of vanadium alone or in binary mixtures, alloys, ores and glass

Abstract

A new rapid, reliable and accurate method is suggested for determination of small amounts of vanadium based on its reduction with excess of thiourea in slightly acidic medium whereupon the yellow vanadium (V) is determined. The unreacted thiourea is determined with Hg (II) potentiometrically in presence of Ag / amalgam as indicator electrode coupled with S.C.E. The method finds application for the determination of vanadium in some industrially important products .
