چکیده انگلیسی
The combined process of electro-catalytic oxidation and de-colorization of wastewater contained Methyl Orange (MO) in a double-anode system, with iron plate and graphite plate as anodes and graphite plate as cathode assisted by Co2O3-CuO-PO43â modified kaolin, was investigated systematically. The effects of pH, current density and electrolyte on de-colorization efficiency were also studied. Chemical oxygen demand (COD) was selected as another parameter to evaluate the efficiency of this combined degradation method on treatment of MO wastewater and the results revealed that when initial pH was 5.0, current density was 30 mA cmâ2, NaCl as electrolyte and its concentration was 2.5 g dmâ3, the color removal efficiency and COD removal can reach 100% and 89.7%, respectively. Meanwhile, the kinetics and the possible mechanism were also discussed.
