摘要
为了探索磁性木质素基活性炭对亚甲基蓝的吸附性能和机制,采用化学共沉淀法制备木质素基磁性活性炭,考察了该磁性活性炭对亚甲基蓝的吸附性能。结果表明:该活性炭吸附亚甲基蓝的过程符合Langmuir吸附等温模型,吸附动力学符合用Elovich模型。磁性木质素基活性炭吸附亚甲基蓝是化学吸附为主的单分子层吸热过程。
In order to explore the adsorption performance and mechanism of magnetic lignin based activated carbon for methylene blue,lignin based magnetic activated carbon was prepared by chemical coprecipitation method,and its adsorption performance for methylene blue was investigated.The results showed that,the adsorption process of methylene blue on the activated carbon conformed to Langmuir adsorption isotherm model,and the adsorption kinetics conformed to Elovich model.The adsorption of methylene blue on magnetic lignin based activated carbon was a single molecular layer endothermic process dominated by chemical adsorption.
