The paper describes a study on electro-oxidation of cyanides complexed with copper, present in metal plating wastewater. A detailed voltammetric study has indicated that formation in situ of the electrocatalytic film of copper oxide and electro-oxidation of cyanides probably occurs at the same anode potential. By contrary to other materials at which electro-oxidation of cyanide also occurs, at copper oxide elimination of cyanide occurs at a potential lower then the potential of hydroxide ion discharge.
