A simple, sensitive, and selective method for rapid determination of nitrite is described which is based on its catalytic effect in the reaction between thymol blue and bromate in acidic media. The reaction is monitored spectrophotometrically by measuring the decrease in absorbance at 543 nm by a fi

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
A catalytic spectrophotometric method for the determination of trace amounts of bromide is proposed. In acidic solution 4,4'-bis(dimethylamino)diphenylmethane (tetrabase) is oxidized by chloramine T to form a blue compound, which is further oxidized to a greenish-yellow compound. The reaction is acc
