Title: Study on Cr(VI)-potassiumbromate-ethyl violet system of determination trace Cr(VI) and its analytical application
Abstract: A new catalytic kinetics spectrophtometry of determination trace amounts chromium(Ⅵ) is built,which is based on catalytic effect of chromium(Ⅵ) by indicating fadeness reaction of potassium bmmate oxidation ethyl violet.This method is of linear rang 0.004~0.094 μg/mL and determination limit 1×10~ -9 g/mL.I’t can be used to detect trace amounts chromium(Ⅵ) in water.
