In this work, simultaneous determination of two groups of elements consisting of Pb (II)–Cd
(II) and Cu (II)–Pb (II)–Cd (II) using adsorptive cathodic stripping voltammetry are described.
The method is based on accumulation of these metal ions on mercury electrode using
xylenol orange as a suitable complexing agent. The potential was scanned to the negative
direction and the differential pulse stripping voltammograms were recorded. The
instrumental and chemical factors were optimized using artificial neural network. The ...
