Abstract
AbstractProcedures are given for the electrometric determination of vanadium in alloy steels. In tungsten‐free steels vanadium is determined by titration with ferrous sulphate under specified conditions of acidity. It is shown that this method gives low results for steels containing tungsten, due to the incomplete reduction of the vanadophosphatotungstate complex; complete reduction however takes place by boiling with excess ferrous sulphate, enabling the determination to be finshed by electrometric titration with standard permanganate. Small amounts of vanadium accompanied by large amounts of tungsten can only be determined by titration with ferrous sulphate when the amount of phosphoric acid is greatly increased.
