Simultaneous Removal of Cyanide and Heavy Metals Using Photoelectrocoagulation

One of the new methods used to remove contaminants from effluent is electrocoagulation method, which sometimes combined with other increase removal efficiency contaminants. To simultaneously nickel, cyanide, zinc, and copper, method photo-electrocoagulation was along an oxidizing agent, namely hydrogen peroxide (Hp). In addition, effects factors affecting were studied, including pH, electrode arrangement, current intensity. An electric 300 mA at a pH 10 for 60 min, Fe-SS electrodes distance between them 5 cm, rate 4 mg/L ideal conditions needed accomplish photo-electrocoagulation-oxidation process. According these study findings, when photocatalyst-electrocoagulation-oxidation (Hp) used, highest efficiencies copper 85, 96, 94, 98%, respectively. The results showed that using increased simultaneous pollutants by 10% compared conventional method. reason in production hydroxyl radicals formation coagulants produced
