Electrochemical destruction of dilute cyanide by copper-catalyzed oxidation in a flow-through porous electrode
Aqueous cyanide-ion concentrations can be reduced from 100 ppm to below 1 ppm by oxidation in a porous flow-through reticulated vitreous carbon anode catalyzed by copper. proper control of solution pH combined with potentiostatic operation maintains high current efficiency. A theoretical model that accounts for interactions between mass transfer and chemical reactions is capable of describing process performance.
