摘　　要：活性炭纤维的吸附性能和其表面官能团密切相关。远程等离子体处理是活性炭纤维获得更好的表面改性的新方法。为了提高活性炭纤维对水中有机污染物的吸附性能,本文对粘胶基活性炭纤维进行了远程等离子体表面改性,探讨等离子体处理时间,远程区距离对活性炭纤维的减重率及吸附性能的影响。结果表明,在远程区等离子体中电子离子对样品的刻蚀作用被抑制,同时远程区等离子体处理的吸附剂对水中有机污染物的去除效果优于未处理试样。The adsorption performance of activated carbon fibre (ACF) is closely related to its surface functional group. The treatment with long-range plasma is a new method to acquire better surface modification for ACF. In order to improve the adsorption efficiency against the organic pollutions in water, the surface modification for the viscose ACF was carried out with long-range plasma; the effects of treating time with plasma and long-range distance on weight decreasing rate of ACF and adsorption performance were investigated. The results showed that, in long-range area, the etching action of electrons and ions to sample was inhibited; meanwhile, the removal effect of the adsorbent treated with plasma in long-range area on organic pollutants in water was superior to the sample without any treatment
