Аннотация:Specific features of the copper and oxygen adsorption on electrolytic palladium deposits obtained from chloride solutions at different deposition potentials are considered. It is shown that, in sulfuric acid solutions, the palladium dissolution, which accompanies the oxygen adsorption, obscures the adsorption behavior of the deposits with respect to oxygen. Assumptions are made about the predominant crystallographic orientation (100) of the surface of some palladium deposits being dependent on the deposition potential and about the presence of regions whose adsorption properties are anomalous with respect to copper. The assumptions are based on a comparative analysis of the copper adsorption data and X-ray diffraction patterns. In addition to sites of crystalline palladium, the deposits are found to have disordered areas as well.
