โœฆ Synopsis

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 coulometry at O-45 V us N.H.E.) indicated that two moles of hydroxyl ion and two faradays electricity were consumed during anodic oxidation of one mole of cyanide.

Several consecutive reaction paths for the oxidation of cyanide were proposed on the basis of the above diagnostic criteria. Among them, the mechanism invoking metal peroxide would be available in view of the chemical properties of several intermediate species.
