| Abstract/Summary |
The complex formation and extraction of chromium(VI) with Cationic Yellow 42 dye reagent has been investigated by the spectrophotometric method. The influence of the medium acidity, concentration of the ligand, and of the dye reagent on the absorbable of the coloured extract bas been studied. The optimum conditions have been found: 0.3-0.9 mol dm-3 H2SO4, 0.6 mol dm-3 NaBr, (2.2-2.6) × 10-4 mol dm-3 CY 42.
