- ... This paper describes a new, simple, sensitive and selective catalytic kinetic spectrophotometric method for trace amount determination of vanadium(v) in food samples. The method is based upon the catalytic effect of vanadium(v) on the oxidation of Janus Green by bromate in sulfuric acid media. The reaction was followed spectrophotometrically by measuring the decrease in absorbance of Janus Green a ...
