摘　　要：本文考察了PAN基活性炭纤维（ACF）床层对低浓度有机溶剂蒸汽的吸附行为，并应用了Yoon—Nelson理论，发现穿透曲线可用改进的方程式来表达，得到了吸附剂ACF2的吸附常数及三氯乙烯、甲苯的总吸附传质系数。The breakthrough characteristic of organic solvent vapor on PAN based ACF beds was investigated. It was found that the breakthrough curves can be described by the modified Yoon - Nelson equation. The adsorption constants and overall mass transfer coefficients were obtained and compared with those of granular activated carbon.
