Abstract
A method, analogous to that used for studying overlapping bands in absorption spectroscopy, has been developed for the quantitative analysis of overlapping anodic-stripping voltammograms. Six simultaneous equations were formulated to resolve general overlapping voltammograms. When the second species is not oxidised at the peak potential of the first species these six equations are reduced to four. Provided that the oxidation currents are additive, this approach is not limited by the degree of overlap. The method has been shown to be satisfactory by studying the cadmium-lead pair as an example.
