| Abstract: | A new catalytic spectrophotometric method for the determination of traceamountsof vanadium is proposed. The method is based on the vanadium catalysed oxida-tion reaction of metanil yellow by potassium bromate. The range of determination is 0~6ng/ml,detection limit is o. 15ng/ml for vanadium. This method has been applied to thedetermination of trace vanadium in human hair and food with satisfactory results. |
