摘要：

Chromium(VI) gives a pink coloured solution in chloroform in the presence of ferron when extracted from slightly acidic medium. This reaction is used for the spectrophotometric determination of chromium by measuring the absorbance at 510 nm. Beers law is obeyed in the range of 5-70 mug/ml. Most of the important metal ions do not interfere. The relative standard deviation is 2.78%.
