Abstract
Generation of hydrogen cyanide at the anode in a chromium (III) - thiocyanate plating bath, resulting from oxidation of thiocyanate anions, is prevented by an additive to the electroplating solution which oxidizes at the anode in preference to the thiocyanate, and whose reaction products will not adversely affect the cathode reaction. Such an additive is potassium iodide.
