The mechanism of anodic oxidation of cyanide on platinum electrode was studied electrochemically and chemically. Cyanide was oxidized at a first order with respect to hydroxyl ion and at zero with respect IO cyanide ion on the rate determining step. On the other hand. the potential controlled coulom

β¦ Synopsis
The oxidation processes of cyanide and cyanate ions on a Pt electrode in aqueous and methanol solutions were studied by infrared spectroscopy. In aqueous solution, the cyanide ion was oxidized to cyanate and successively to carbon dioxide. The reaction proceeded on an oxidized platinum surface. In methanol solution, HNCO is the main product during anodization.

Cyclic voltammetry experiments performed in acid solutions of cyclohexene on platinized platinum anodes show that platinum oxide must play a role in the anodic oxidation of the hydrocarbon through a mechanisticscheme of the type proposed by Gilman[lO].
Abstmct-The relation between the oxide coverage of a platinum electrode and the adsorption of yttrium ions on to it has been studied in a system where both are measured without removing the electrode from the experimental solution. The oxide coverage was measured by reductive chronopotentiometry and
