摘要：
Effective values of exchange current i(0), cathodic and anodic transfer coefficients alpha and beta, and cathodic and anodic reaction orders with respect to cyanide ions (P-c, P-a) are measured in cyanide silver-plating electrolytes at different surface coverages by lead adatoms theta. With increasing coverage, i(0) and alpha increase from 5 x 10(-5) A cm(-2) and 0.24 in pure solutions to 8 x 10(-5) A cm(-2) and 0.3 at theta = 0.4, with P-c and P-a hardly altering. The cathodic process markedly accelerates at theta = 0.6, while at theta = 0.5 the kinetics of the cathodic process is unstable. Different effects of lead adatoms on cathodic and anodic gold and silver plating in cyanide solutions are due to lead salts not affecting the metal substrate dissolution mechanism in the latter case.
