摘要：

Ti/SnO2+Sb/PbO2 anode was prepared by combination technology of thermal decomposition and electrodeposition. The properties of the interlayer and activated layer of electrode were studied, and the anode electrochemical behavior was examined as well. The ammonia in coking wastewater was treated by electrochemical oxidation method using Ti/SnO2+Sb/PbO2 as anode. The effects of operating parameters including current density, anode material, pH and the concentration of chloride were inspected by orthogonal array experimental design. The results showed that anode material, current density, and chloride concentration have significant influences on the ammonia removal, and 250mg/L ammonia was removed totally within 60 minutes on Ti/SnO2-Sb/PbO2 anode at 0.05A/cm(2) current density. The Ti/SnO2-Sb/PbO2 is a promising anode material for electrochemical coking wastewater treatment.
