摘要: A kinetic method has been developed for the spectrophotometric determination of subnanogram per milliliter levels vanadium in presence large amounts sodium chloride. The is based on catalytic effect vanadium(V) oxidative coupling N,N-diphenylhydrazine with chromotropic acid bromate. In this reaction, chloride enhanced catalysis vanadium(V). Vanadium(IV) could be also determined because its oxidation by By measuring change absorbance dye produced at a fixed time, vanadium(IV) and range 0.01–0.2 ng mL−1 determined. relative standard deviation was 2.0% ten determinations 0.1 ng Interferences from diverse ions suppressed use ethylenediamine-N,N,N′,N′-tetrakis(methylenephosphonic acid) as masking agent. successfully applied to chloride-rich samples.
