Fundamental study has been performed for synthesis of silver cyanide through electrochemical
leaching process. Silver was used as anode, stainless steel (STS 316) as cathode and proton exchange
membrane (Nafion 117) as a separator between electrodes. Concentration of silver leached was
analyzed by ICP-OES. Surface and cross section were analyzed by SEM and EDS. After 20 min,
19.4% leaching of silver at standard condition (voltage alone, no stirring and air-bubbling), 70 % in
stirring, 80.9% in air bubbling were measured. Electric current efficiency in air-bubbling was 102%,
which means chemical dissolution as well as electric leaching was done during reaction. After
reaction, silver ions were not detected in cathode electrolyte. Dissolved silver ion might directly react
with cyanide ion to make negative complex silver cyanide ion that can not penetrate proton
exchange membrane.
