Open publisher page 0 citations

Abstract

In this paper a new catalytic method for determining trace Chromium has been studied.Chromium(VI) can catalyze the decolorization oxidation of acid chrome blue k.by crossing the sulphuric acid potassium.The detection limit of this method is 7.79×10 -6 g·L -1 .The linear range of determination is 0～8.0ug/50mLCr(VI).The method has been used to determine trace Cr(VI)in electroplation wastewater with satisfactory results.
