No full textA comprehensive investigation of the spectrophotometric determination of beryllium with Chrome Azurol S is described. At pH 4.6, and in the presence of EDTA, only Cr-3+ and F1- ions interfere seriously. A molar absorptivity of 4060 at 569 mu has been found for the complex, with a standard deviation of plus or minus 0.4 per cent at the 25 omega g beryllium level. Chrome Azurol S has several advantages over Berillon II, which is widely used for the spectrophotometric determination of beryllium
