The specific adsorption of 36Cl-labelled Cl- ions and 35S-labelled HSO4- ions was studied in 1 mol dm-3 HC1O4 supporting electrolyte in the presence of Cd2+ ions at a gold support over a wide potential range corresponding to electrodeposition, alloy formation, underpotential deposition of Cd species and existence of an adatom-free surface. The distinct sections in the potential dependence of the adsorption of anions together with the potential versus time curves obtained under open circuit conditions reflect the changes in the state of the electrode surface, the dissolution of the bulk Cd phase and the slow elimination of Cd species from the Cd/Au alloy.
