The direct and indirect determination of cyanides can be carried out with a silver iodide-based ion-selective electrode. The electrode measures only cyanide ions and does not respond to hydrocyanic acid. A detailed study of metal-cyanide complexes shows that the cadmium and zinc cyanide complexes can participate in the exchange reaction on the membrane surface, but that metal cyanide complexes of higher stability than silver dicyanide have no effect on the electrode. The cyanide-sensitive electrodes can be employed for continuously recording the cyanide content of effluents.
