Abstract / Full Text

It is shown that the kinetics of electrochemical processes in a copper-thiocarbamide solution is of mixed character. The effective cathodic and anodic transfer coefficients Β = 0.25 and α = 0.4, reactions orders with respect to the ligand 0.7 and 1.5, and the exchange current densityi 0 ≅10-4 A/cm2 are determined. Using the literature data on the thiocarbamide adsorption on copper, the results are interpreted as evidence for the involvement of one thiocarbamide molecule from the bulk solution, along with the adsorbed ligands, in an elementary act of copper dissolution.
