摘　　要：以纸巾为前驱体通过NaOH化学活化制备活性炭纤维,扫描电镜观测其微观结构为多孔纤维状。通过活性炭纤维对亚甲基蓝的吸附实验研究活性炭纤维吸附动力学,Pseudo-second-order方程比Pseudo-first-order方程更适于吸附数据模型,相关系数高达0.998,所制备活性炭纤维对亚甲基蓝最大平衡吸附量为200mg/g。The activated carbon fibers from paper were prepared by chemical activation with NaOH. SEM results indicated the sample exhibits fiber structure with lots of micropores. The kinetic model of Pseudo-second-order equation is more fitter than Pseudo-first-order equation for methylene blue （MB） adsorption onto the activated carbon fibers. The adsorption rates were found to conform to the pseudo-second-order kinetics with high value of the correlation coefficients （R 0.998）. The Maximum MB adsorption capacity at equilibrium is 200 mg/g.
