摘　　要：采用吸附法去除室内挥发性有机污染物VOCs,以活性炭纤维(ACF)作为吸附剂,用苯、甲苯作为VOCs的代表物,对影响活性炭纤维吸附性能的入口气体浓度、气体混合、物化性质、填充密度等因素进行了探讨.实验结果表明,初始浓度大则穿透时间短;甲苯比苯更易被吸附;苯和甲苯混合吸附时,吸附能力强的甲苯有置换吸附能力弱的苯的现象发生;填充密度对穿透时间与饱和时间有影响,密度大利于吸附.VOCs indoor after removed with activated carbon fiber was determined, in which benzene and toluene were used as representatives of VOCs. The results showed that the breakthrough time decreased with arise in initial concentration, and the adsorption of toluene was easier than that of benzene. It was happened that the benzene adsorbed in activated carbon fiber could be replaced by toluene when the mixture of benzene and toluene was adsorbed. The increased filling density was favored on adsorption.
