A laboratory-scale electrolytic cell with a Ti/RuO2-Pt anode and a Ti cathode was developed to treat high concentration cyanide-contained wastewater. The effects of the different electrode distances, concentration of chlorine anion, current densities, and the value of pH on the CN^- removal were investigated. The results shown the optimum experimental condition was set at the electrode distance of 9cm, NaCl dosage of 0.5g/L, the current density of 10 mA/cm², and pH of 12. At the optimum experimental condition, the CN^- concentration in the solution decreased from 150.33 mg/L to 1.20 mg/L, and the CN^- removal efficiency reached 99.2%.
