Enhancement of electrochemical oxidation of Cu(CN) 3 2− by the peroxydisulfate oxidation

In this work, the peroxydisulfate (PDS/K2S2O8) enhancement of electrochemical oxidation of Cu(CN)32− with the RuO2/Ti mesh anode and the stainless steel cathode was investigated. The removal efficiency of cyanide was largely increased with increasing the PDS concentration. When the concentration of K2S2O8 was 1.00 mM and the current density was 14.80 A/m2, the removal efficiency of cyanide was increased from 34.3% to 89.1% at the initial 10 min....
