摘　　要：研究了不同预处理方法下活性炭纤维对甲苯的等温吸附,以评价预处理方法对其吸附性能产生的影响,结果表明:经(1+9)HCl处理的ACF及蒸馏水蒸煮处理过的ACF与未处理的ACF相比,对甲苯的吸附性能有十分显著的提高;处理后的ACF在35℃时的甲苯吸附量仍明显高于未经处理的ACF在25℃下的甲苯吸附量。The toluene adsorption behavior of activated carbon fibers （ACF） with different pretreatments was investigated by an isothermal operation method in order to evaluate the adsorption performance affected by pretreatments. Results showed that the toluene adsorption capacity of the ACF treated by （1 ＋ 9） chlorhydric acid and the distilled water was remarkably improved when compared with that of the untreated ACF. The treated ACF may even have a much higher toluene adsorption equilibrium amount at 35℃ than the untreated ACF at 25℃.
