ABSTRACT
A new approach, based on non-aqueous capillary electrophoresis separation and indirect photometric detection, was established for the determination of the transition metal ions Pb2+, Zn2+ and Cd2+. Under optimized conditions, the method produced baseline separation of these three metal ions. The linear range and detection limits were 10 âˆ¼ 50 ÂµM, 1.9 ÂµM for Cd2+; 10 âˆ¼ 50 ÂµM, 2.1 ÂµM for Zn2+; and 20 âˆ¼ 100 ÂµM, 3.8 ÂµM for Pb2+, respectively.
