| Abstract: | Isothipendyl hydrochloride is proposed as a selective and sensitive reagent for the rapid spectrophotometric determination of vanadium(V). The reagent instantaneously forms a red coloured species with vanadium(V) in phosphoric acid medium which exhibits maximum absorbance at 500 nm with Sandell's sensitivity of 6.55 ng cm-2. Beer's law is valid over the concentration range of 0.2-4.8 ppm with an optimum concentration range of 0.4-4.5 ppm. The method has been successfully applied to the analysis of vanadium steels and minerals. |
