A study of the adsorption of cadmium(II) on mercury from thiocyanate solutions by double potential-step chronocoulometry

The adsorption of Cd(II) in thiocyanate solutions has been studied by a double potential-step chronocoulometric method. The amount of Cd(II) adsorbed decreases as the electrode potential is made increasingly cathodic. The amount of adsorbed Cd(II) was also studied as a function of the concentration of thiocyanate. The double potential-step chronocoulometric method permits an accurate double-layer capacity correction and appears to be the best faradaic method for the determination of adsorbed reactant.

Application of double potential-step chronocoulometry to the study of reactant adsorption. theory

The theory of a new technique for the study of reactant adsorption is developed. It is shown that a rigorous double-layer correction can be made and that a quantitative determination of the amount of reactant adsorption is possible. By combination of this technique with other methods, such as the drop-extrusion method, for the determination of double-layer charge, it is possible, in some cases, to determine the amounts of both reactant and product adsorbed.

AbstractThe influence of the double layer on the overall rate of electrochemical processes controlled by a prior volume chemical reaction is discussed in terms of the ratio between the equivalent thicknesses of the reaction layer and of the diffuse part of the double layer. The influence of potential and ionic strength on the polarographic waves of Cd(CN)4− and Ni++ has been interpreted by the proposed theory.
