Vanadox--a new reagent for the photometric determination of vanadium.
A new reagent, 2,2-dicarboxydiphenylamine, vanadox, is proposed for the photometric determination of vanadium in steels, high temperature alloys and ferrotitanium ores. In strongly acidic medium the reagent is selective for vanadium(V) and only eerium(IV) interferes.
