A stopped flow injection-catalytic spectrophotometric method for the determina tion of trace amounts of vanadium was proposed based on the catalytic effect of vanadium on the oxidation of malachite green with KBrO3 and tartaric acid as an activator in HAc medium.The range of determintion is 20～200μg/L for vanadium. The method has been applied to the determination of trace vanadium in food with satisfactory results.
