✦ Synopsis

The electrochemical oxidation of cyanide ion with and without coexistent metallic ions was studied The PbO,-electrodeposited Ti anode was suitable for the purpose. The process required an excess amount of OH-since otherwise azulmin was formed by the side reaction. The interference effects of metallic ions (Cd, Cu, Fe and Zn) on the oxidation ofcyanide were investigated. Of these, Fe ion was the most harmful.

Ti/SnO, + CuCo,O, and Ti/RuO, + TiO, anodes were used to study oxygen evolution in alkaline solutions and to compare the kinetics on both electrodes. On each electrode the existence of two Tafel regions was confirmed. At low current density (cd) the Tafel slope is 39mV decade-', whereas at high cd i

The anodic film studied was formed on Pb + 9at.%Bi at 0.9V (vs. Hg/Hg,S03 in 4.5 M H, SO, solution (25°C). The change of the phase composition of the anodic film during reduction at -0.91 V (vs. Hg/Hg,SO,) (slightly more positive than that of the reduction potential of PbSO,) was determined by X-ray
