摘　　要：由化学药品磷酸盐催化处理的粘胶纤维在氮气气氛下于８２０℃下炭化，随后用水蒸汽活化制得粘胶活性炭纤维。采用液氮７７．４Ｋ下的吸附测定了该纤维的吸附等温线和常温下的静态苯吸附量以研究其吸附性能，并对其孔结构诸如比表面积、孔容、微孔容等进行了表征。Rayon activated carbon fibers(ACF) were prepared from rayon fibers treated with chemical regent phosphate, carbonized in nitrogen up to 820℃, and subsequently activated in steam . Nitrogen adsorption isotherms at 77.4K were measured. Static adsorption capacity for benzene at ambient temperature was measured to investigate adsorption properties of rayon ACF. Porous structure parameters such as specific surface area, pore volume and micropore volume and so on were characterized by the different methods.
