| 摘 要： | 目的]探讨Cu／Fe双金属去除四氯化碳的性能。方法]以四氯化碳（cT）为靶污染物，采用分批试验研究了Cu／Fe双金属去除CT的可行性，并研究了铜化率、投加量及pH对CT去除效果的影响；采用柱试验考察了Cu／Fe双金属去除CT的长效性。结果]Cu／Fe双金属对cT有良好的去除性能，CT终去除率可达97．90％；在试验条件下，铜化率越高、投加量越大，Cu／Fe双金属对cT去除效果越好；偏酸性环境有利于Cu／Fe双金属对cT的去除；对于CT的去除，Cu／Fe双金属比零价铁更具有长效性，其寿命是零价铁的2倍以上。结论]为双金属脱氯研究提供了理论依据。

| Abstract: | Objective] The aim was to study the removal of carbon tetrachloride (CT) by Cu/Fe bimetal. Method] The feasibility and influencing factors (Cu ratio, dosage and pH) of the removal of CT by Cu/Fe bimetal were studied by batch experiment, and the long-term performance of Cu/Fe bimetal was studied by column test. Result] Cu/Fe bimetal had a good performance in CT removal, with an overall CT removal rate of 97.90%. Cu/Fe bimetal with higher Cu ratio and bigger dosage brought better removals of CT.
