Abstract

The effect of thallium(I) ions on the rate of anodic dissolution of gold in cyanide solutions is studied by measuring the potential and time dependences of the current. The extreme nature of the dependences is attributed to a maximum catalytic effect, which is presumably connected with reaching a certain ratio between the surface coverages by thallium adatoms and cyanide adions, and to a complicated potential dependence of the process rate constant in the presence of thallium adatoms
