Abstract: The determination is discussed of Cr(III) and Cr(VI) in dyes by LC on a column (25 cm x 4.6 mm) of Hypersil ODS with a mobile phase (2 ml/min) of tetrabutylammonium sulfate of pH 6.75/acetonitrile (4:1) with detection at 380 nm, by AAS at 357.9 nm and by dialysis followed by AAS or ICP-AES. Trace impurities in Cu were determined using ICP-MS with In as internal standard and FIA in a dilute HNO3 carrier stream with solvent extraction. Results were compared to certified values of reference materials. Results are tabulated for the determination of Ag, As, Bi, Fe, Pb and Sb.
