| Abstract: | Methdilazine hydrochloride has been used as a sensitive and selective reagent for the rapid spectrophotometric determination of chromium(VI). The reagent gives a red coloured species instantaneously on reaction with chromium(VI) in phosphoric acid medium and exhibits maximum absorbance at 512 nm with Sandell's sensitivity of 3.1ng cm-2. Beer's law is obeyed over the concentration range of 0.1-1.8 ppm; the optimum concentration range is 0.2-1.6 ppm. The method has been successfully applied to the analysis of chromium(VI) in steels and soil samples. |
