| Abstract: | 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. |
