Abstract

The anodic behaviour of silver, copper, palladium, gold, platinum and glassy carbon (GC) electrodes has been studied in concentrated halide solutions in dimethylsulfoxide (DMSO) using linear sweep voltammetry, coulometry, chronoamperometry and X-ray diffraction. Parallel studies in perchlorate and aqueous solutions were used to interpret the data. Only solution oxidation was observed at Pt and GC, but Ag, Cu, Pd and Au were found to oxidize more readily in DMSO than in aqueous solution. The relative merits of DMSO and aqueous halide solutions for the electrorefining of these metals are discussed briefly.
