摘　　要：用壳聚糖制成活性炭,研究其对亚甲基蓝的吸附能力,并分析了吸附动力学以及吸附等温线。结果显示,壳聚糖质活性炭对亚甲基蓝最佳的吸附条件为:投入量为0.3 g,吸附时间为60 min,亚甲基蓝体积为10 mL;吸附温度为50℃,吸附过程较为符合二级吸附动力学方程、Freundlich模型。Use chitosan to make activated carbon. It studied the effect on the adsorption capacity of meth-ylene blue,and analyzed the adsorption kinetics and the adsorption isotherm. The results showed that the best adsorption conditions of methylene blue optimum for chitosan activated carbon：crosslinking agent a-mount of 0. 3 g,adsorption time of 60 min,the volume methylene blue of 10 mL,adsorption temperapure of 50℃. The adsorption process coincided with the second order kinetic,Freundlich model could describe the process properly.
