The adsorption of labelled Ca2+ ions was studied at platinized platinum electrodes in 1 x 10t-2 mol dmt-3 HClO4 supporting electrolyte in the absence and presence of organic additives containing -COOH or -SO3H groups (benzenesulfonic, maleic, glyoxylic, succinic acids etc). It was found that molecules which forms strongly chemisorbed species induce a significant adsorptiuon. The phenomenon is explained by an ion-exchange process occuring with the -COOH and -SO3H groups anchored to the surface via the strongly chemisorbed species.
