Abstract

An electrolyte system, using malic acid as a complexing agent, has been developed to allow the determination of transition metal cations using miniaturised isotachophoresis. The method allowed the simultaneous determination of Mn 2+, Cr 3+, Fe 2+, Co 2+, Zn 2+ and Ni 2+ to be made without interference from other common ions. Limits of detection were calculated to be in the range 0.5-1.0 mg l -1 for Mn 2+, Cr 3+ Co 2+and Zn 2+ and 2.0 mg l -1 for Fe 2+ and 4.7 mg l -1 for Ni 2+. The successful analysis of five industrial samples, containing a range of these metal ions, obtained from metal processing plants were achieved in under 13 min. The separations were performed on a poly(methyl methacrylate) chip with integrated platinum wire conductivity detection electrodes. © 2004 Elsevier B.V. All rights reserved.
