Abstract

The quantitative determination of chromium(VI) by separation from chromium(III) complex of 8-hydroxyquinoline using solvent extraction has been studied. The reaction conditions for chromium(III) complex of 8-hydroxyquinoline and the solvent extraction of complex were investigated in detail. The chromium(III) complex was extracted with organic solvent (n-hexane) and residual chromium(VI) was determined by ICP-AES in aqueous layer. This technique is quantitative in the pH range of 8-9 and the limitations such as interfering ions were discussed.
