摘　　要：不同活化条件下,以磷酸为活化剂制备粘胶基活性碳纤维(VACF),研究VACF对甲硫醚静态吸附的效果·随着活化温度的升高,活性碳纤维对甲硫醚的吸附率增大;碳化活化时间达1h后,活性碳纤维对甲硫醚的吸附性能没有明显变化;活化剂浓度为1:3(磷酸与水体积比)、浸泡的时间为10h时,活性碳纤维对甲硫醚的吸附效果最佳.Phosphoric acid used as an activator, the effect of dimethyl sulfide adsorbed statically by different preparation condition of viscose-based activated carbon fiber （VACF） were investigated. The experimental results indicate that yield ratio of VACF becomes lower and adsorption ability of ACF to dimethyl sulfide towards better under higher activated temperature. There isn＇t obvious difference in adsorption ability of VACF to dimethyl sulfide after the activated time exceeds 1h. The absorbing effect of VACF to dimethyl sulfide can reach best when the concentration of the activator is 1 ： 3 （ phosphoric acid： water） , and the immersion time is 10h.
