1 97/2 水環系 陳俊成 副教授 期刊論文 發佈 Effect of anions on electrochemical coagulation for cadmium removal , [97-2] :Effect of anions on electrochemical coagulation for cadmium removal期刊論文Effect of anions on electrochemical coagulation for cadmium removalHuang, Chien-hung; 陳俊成; Chen, Luke; Yang, Chen-lu淡江大學水資源與環境工程學系Electrochemical coagulation;Sulfate;Nitrate;Chloride;Anodic dissolution;CadmiumElsevierSeparation and Purification Technology 65(2), pp.137-146Solutions of nitrate, sulfate, chloride and their combinations were prepared and tested in a parallel plate electrochemical cell to study their effect on electrochemical processes. Among the parameters studied were conductivity, current, current efficiency, pH change, coagulant formation, and cadmium removal. Nitrate ions were able to sustain a healthy current in the cell. The current dissolved aluminum from the anode, dissociated water molecules on the cathode, and increased pH in the solution. Due to excessive pH, Al(OH)4− became the dominating species and therefore no coagulant was observed. In sodium sulfate solutions, the aluminum anode quickl
