摘要: Abstract Combined EQCM and voltammetric studies in conjunction with radiotracer adsorption investigations were carried out order to obtain direct information on the interfacial behavior of Cu 2+ –Cu system under equilibrium dynamic conditions aim clarifying role participation + ions formed by interaction cupric copper metal. The appearance accumulation solution phase is clearly demonstrated through experiments using labeled Cl − ions. formation bulk CuCl preceded a surface layer. Data obtained from combined allow us separate potential regimes where electrosorption, or ions, dissolution are predominant processes.
