摘　　要：研究了ＰＡＮ基活性炭纤维（ＡＣＦ）的吸脱附性能。结果表明，ＰＡＮ基ＡＣＦ的吸附具有微孔吸附的特征，它对有机溶剂蒸汽有较高的吸附容量和极快的吸附／脱附速度。在吸附时，ＰＡＮ基ＡＣＦ呈现出明显的分子筛效应。The adsorption/desorption properties of PAN based activated carbon fiber were studied.It was found that the adsorption isotherm of this kind of ACF had the characteristics of micropore adsorption. ACF had large adsorption capacity to solvent vapros,and also very fast adsorption/desorption rate.Molecular sieveing effect of the ACF based PAN was found during adsorption.
