摘　　要：为了解抗坏血酸有机酸类去污剂对核电站化学去污的电化学行为,提高其去污效果,通过Nafion溶液的固定作用,将核电站管道中的主要腐蚀产物Fe3O4制作成化学修饰电极.通过三电极体系研究其电化学行为,考察了其扫描速度的影响、溶液浓度的影响和反应的类型.同时进行了循环伏安曲线、极化曲线和交流阻抗等测试.分析了其电化学行为,得到了一系列电化学数据.In order to understand the electrochemical behavior of ascorbic acid organic acid detergent for chemical decontamination of nuclear power plant and improve its decontamination effect,the main corrosion product (Fe3O4 ) in the pipelines of nuclear power plant was made into a chemically modified electrode by the fixing action of Nafion solution in this paper.The electrochemical behavior of Fe3O4 in ascorbic acid was studied by three-electrode system.The effects of scanning speed,solution concentration and reaction type were also investigated.At the same time,tests such as cyclic voltammetry,polarization curves and AC impedance were also performed.The electrochemical behavior of Fe3O4 in ascorbic acid was analyzed and a series of electrochemical data were obtained.
