Description

technical field [0001] The present invention relates to a kind of preparation method of foamed nickel electrode, relate to a kind of preparation method of the catalytic electrode of hexadecyltrimethylammonium bromide (CTAB) doping with foamed nickel as the matrix in particular, mainly used Removal of chlorinated organic compounds in water by electrochemical reduction. Background technique [0002] Chlorinated organic compounds are widely used as wood preservatives, rust inhibitors, herbicides, fungicides and papermaking industries. They have foul smell, peculiar smell and high toxicity. They are also used for the prevention and treatment of schistosomiasis in Asia, Africa and South America. Among them, 2,4-dichlorophenol and 2,4,5-trichlorophenol are also widely used in the production of pesticides 2,4-D and 2,4,5-T, so the production scale of chlorinated organic compounds in many industrialized countries very large. In addition, in the presence of some organic substances,...
