Applications involving oxidation with KBrO3 rapid potentiometric methods for vanadium alone or in mixtures

ABSTRACT

A RAPID and reliable method is given for the determination of vanadium based on oxidation of the V [IV] with a known excess of bromate to V[V]. The unreacted oxidant as well as V[V] are subsequently reduced with sulphurous acid to V [IV]. The resulting Br was potentiometrically titrated with Hg [I] using silver amalgam as the indicator electrode. The method finds application to the analysis of some binary and ternary mixtures
