| 摘 要： | 采用循环伏安法和恒电流电解法研究了碱性水溶液中三氯乙酸在活性银阴极上的电化学还原脱氯反应。实验结果表明：活性银阴极对三氯乙酸的还原脱氯反应具有很高的电催化活性，三氯乙酸在银电极上的还原反应是个分步脱氯过程，主要的路径为三氯乙酸--二氯乙酸--氯乙酸--乙酸。

| Abstract: | Electrocatalytic reductive dechlorination of trichloroacetic acid on activated silver electrodes was studied in aqueous basic solution by cyclic voltammetry （CV） and controlled-current electrolysis Experiment evidence is presented that silver exhibited powerful electrocatalytic activity for selective dechlorination of trichloroacetic acid to less，or non-halogenated acetic acidThe reduction of trichlo-roacetic acid in a stepwise dechlorination fashion was suggested and trichloroacetic acid--dichloroacetic acid--monochloroacetic acid--acetic acid is the main reductive reaction route |

| Keywords: | reductive dechlorination trichloroacetic acid silver electrode wastewater treatment |
