摘　　要：以活性炭纤维(ACF)作为去除废水中四氯化碳(CCl4)的吸附剂。分析了震荡时间、温度、pH、活性炭纤维用量等对吸附效果的影响。结果表明,处理含CCl4废水的理想条件为:pH=1、t=25℃、t=30min,最大的去除率能达到90%。CCl4在活性炭纤维上的吸附规律可用Fre-undlich模式描述。活性炭纤维脱附效果很好,可以重复再生使用。Activated Carbon Fiber（ACF） was used as absorbent of carbon tetrachloride（CCl4） in wastewater. Influence of shaking time,temperature,pH value and dosage of ACF on absorption effect was investigated. The results show that the best conditions for removing CCl4 from wastewater are ：pH value 1, temperature 25℃, reaction time 30min. The most removal rate of CCl4 is 90%. Absorption of CCl4 by ACF can be described by Freundlich model. Desorption of ACF is strong and ACF can be used repeatedly.
