摘　　要：采用循环伏安法在草酸电解质中于铜电极表面修饰聚N-乙基苯胺/十二烷基磺酸钠(PNEA/SDS)复合层。该复合电极呈颗粒紧密堆积的多孔结构。电化学分析结果显示,修饰后的电极在循环冷却水中的稳定性得到提升,同时SDS的掺入使复合电极的稳定性得到进一步改善。以PNEA/SDS复合电极为阳极,304不锈钢为阴极可高效去除循环冷却水中的细菌,以单因素法明确了最佳电化学除菌工艺:电流密度15 A/cm^2,极板间距2 cm,停留时间10 s。Poly(N-ethylaniline)/sodium dodecyl sulfonate composite(PNEA/SDS) was prepared in oxalic acid solution on copper electrode via cyclic voltammetry. The composite layer exhibits a porous structure owing to the tightly stacked particles. Results of electrochemical measurements reveal that polymeric modification could improve the stability of electrode. In addition,the doping of SDS could further contribute to the electrode stability. Using PNEA/SDS as anode,304 stainless steel as cathode,it could efficiently remove the bacteria from circulating cooling water. By the single factor method,the optimal operation parameters were obtained as follows:the current density of 15 A/cm^2,the plates distance of 2 cm,and the residence time of 10 s.
