摘要
以聚丙烯腈预氧毡为原料 ,使用水为活化剂制得活性炭纤维。 2 0℃时 ,考察了活性炭纤维对碘、苯酚和亚甲基蓝的吸附性能 ,并与颗粒活性炭的吸附性能作了比较。结果表明 :活性炭纤维的吸附能力比颗粒活性炭的吸附能力强 ,吸附速度快 2～ 5倍。表面分析表明 :活性炭纤维表面含有多种官能团 。
H 2O used as activation agents PAN based ACF were produced.lodine adsorption.Benzene adsorption and Methylene blue adsorbed by ACF and GAC were investigated at 20℃.Results show that adsorption property of ACF are better than that of GAC,adsorption speed of ACF are faster 2～5 times than that of GAC.Surface of ACF containes several of kinds functional groups.ACF has good heat stability.
