摘要
通过氨气活化细菌纤维素制备纳米活性炭并探究其对水中对氯苯酚的吸附性能和初始溶液pH和时间等影响因素。采用Langmuir和Freundlich等温线模型拟合。采用SEM和BET等方法对纳米活性炭进行了表征。结果表明:Act-BC活性炭微孔和介孔结构丰富,对p-CP最大吸附容量251.2mg/g,吸附容量高于市售活性炭。吸附数据符合Langmuir吸附等温线。
Nano activated carbon was prepared by activating bacterial cellulose with ammonia gas. Influencing factors for the adsorption of p-chlorophenol in water were investigated, including initial solution pH and solid-liquid contact time. Langmuir and Freundlich isotherm were fitted. SEM and BET were used to characterize the nano activated carbon. The results showed that Act-BC activated carbon had rich microporous and mesoporous structures. The maximum adsorption capacity of p-chlorophenol was 251.2 mg/g, which was higher than that of commercial activated carbon. The adsorption data conformed to the Langmuir adsorption isotherm.
