Abstract
A method allowing the detn. of heavy metal cations using miniaturized isotachophoresis was developed. Sepns. were performed using a chip milled from poly(Me methacrylate) with integrated Pt wire cond. detection electrodes. The use of miniaturized sepns. devices is particularly appropriate for anal. of toxic species, as both the vol. of sample required and the vol. of waste produced are reduced. Particular attention was paid to the detn. of Cd(II) ions. The method developed allowed Cd(II) to be detd. in the presence of other common metal cations including Ca, Mn(II), Co(II), Zn(II), Ni(II) and Pb(II). A limit of detection for Cd(II) is 9 * 10-6 M.
