The electroconcentration of gold(III) and palladium(II) on the electrode surface gives a binary alloy whose components are electrochemically oxidized at almost the same potential. Two methods were proposed for the separation of overlapping anodic peaks: the chemical reduction of gold(III) under UV irradiation and the use of a special computer software built into the analyzer. The results of determining palladium(II) in raw gold ore using stripping voltammetry and two proposed methods of peak separation are compared.
