“…The large length of potential transients in solutions containing no lead ions (curve 1) suggests that the transients are due not only to the increase in the diffusion polarization but to some other processes as well, probably to some transformation of the structure of the interphase layer caused by the slow adsorption kinetics of cyanide ions on silver [12]. The same pattern occurs at other current densities, which were varied in the interval of i/i d from 0.1 to 0.6.…”

Potential transients on renewable gold and silver electrodes in cyanide solutions containing catalytically active ions of lead and thallium are measured. The transients are recorded both on freshly renewed electrodes and on renewed electrodes kept in solution for specified time periods ∆ t . The behavior of transients following a change in the concentration of lead and thallium ions, current density, and ∆ t qualitatively conforms to regularities that could be expected if the catalytically active adatoms were inserted into the deposit similarly to the admixtures. Methods for determining coefficients of capture of such adatoms by the growing metal deposit are suggested. Factors that hamper determination of these coefficients and make it worthwhile to select a method for their determination that would use potential transients are considered. The capture coefficient for the incorporation of lead adatoms in the growing silver deposit is nearly 20 times that for gold.
