Abstract

A radiotracer method was used for the study of the adsorption phenomena on "black" nickel electrodes formed by electrodeposition of nickel ("nickelized" nickel electrode). Adsorption studies were carried out with labelled HCI, H2SO4, H3PO4, thiourea, phenylacetic and acetic acids in 0.1 mol dm-3 HClO4 supporting electrolyte. The potential dependence of the adsorption of these species was determined in the potential range -200 to +200 mV (on the RHE scale). It was found that a significant potential-dependent adsorption occurs at low concentrations (10-3-10-4 mol dm-3) of the species studied in the course of the anodic dissolution of the electrode. It was deserved that the polarization behaviour of the electrode is influenced by the adsorption of the species studied.
