The adsorption of32P labelled phosphoric acid35S labelled sulphuric acid and36Cl labelled hydrochloric acid from 2 × 10-2mol dm-3HClO4supporting electrode was studied at rhodized electrodes (roughness factor values about 150) by a coupled electrochemical and radiotracer technique. A special attempt is made to avoid the problems caused by the reduction of ions. It has been stated that the adsorption behaviour of H2PO4-and HSO4-(SO42-) ions is very similar and the potential dependence of the adsorption can be described by a simple relationship reported previously (G. Horányi and E.M. Rizmayer, J. Electroanal. Chem., 198 (1986) 379; 201 (1986) 187), while the relationship for Cl ions can be conceived as composed of at least two simple functions describing the adsorption of HSO4-(SO42-) ions, with two different sets of parameters.
