| 中文摘要 |
| 采用循环伏安法,对氯代烃在铜电极表面上的电还原特性进行了研究,评价了它们在铜电极上的电还原反应活性,分析了此类化合物在铜电极上的还原机理,并且讨论了电还原反应活性和此类化合物结构之间的关系.结果表明,氯代烷烃和部分氯代芳烃在铜电极表面有还原电位,能在铜电极表面被直接还原.氯代芳烃不易在铜电极上被直接还原.实验结果为催化铁内电解法提供了理论依据. |
| 英文摘要 |
| The electrochemical reduction characteristics of chlorinated hydrocarbons were investigated by applying cyclic voltammetry technique. The reduction mechanism and reactivity of the chlorinated hydrocarbons at the copper electrodes were explored. The relation between the reductive reactivity at the copper electrode and the structures of this kind of compounds was discussed. The experimental results show that chlorinated paraffin hydrocarbons and a portion of chlorinated aromatic hydrocarbons could be reduced directly at the copper electrode; however, chlorinated aromatic hydrocarbons aren't easy to reduced directly at the copper electrode. The results provide a theoretical basis for the catalyzed iron inner electrolysis method. |
