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 .
