| Abstract: | The capillary electrophoretic separation of Fe2+, Co2+, Zn2+ and Ni2+ in a phosphate buffer solution by complexing with 4-(2-thiazolylazo)resorcinol was investigated. The influences of some crucial parameters that included chelating ligand in the electrophoretic running buffer and sample solution, pH value and concentration of buffer were examined. Under optimum conditions (10mmol*l-1 NaH2PO4-Na2HPO4 buffer containing 1×10-4mol*l-1TAR, pH 7.5), a baseline separation of these metals was accomplished within 3 min. The detection limits (S/N=3) ranged from 0.013-0.14 μg*ml-1. The method was applied to analyze trace metal ions in the environmental samples. |
