Cadmium cyanates

CO2 and N2. Excess chlorine gas (i.e., chlorine which did not form hypochlorite) converted the cyanide to cyanate, which was subsequently oxidized by hypochlorite. Cadmium was precipitated from the water due to an increase in the solution pH. A platinum-plated niobium screen was the anode and a stainless steel screen was used as the cathode. At an applied potential of 6.0 V, resulting in a current of 6.0 A, the cadmium concentration decreased from 17.4mg/dm to 0.01 mg/dm, while the cyanide concentration declined from 54 mg/dm to zero in 80 min of cell operation.
