The use of a gallocyanine-bromate oxidation system for the direct determination of vanadium (0.020-100 ng/ml) with spectrophotometric detection is described. The decrease in absorbance results from the oxidation of gallocyanine by bromate in the presence of vanadium as a catalyst. The effects of imp
