摘要
活性炭纤维(ACF)作为一种新型活性炭吸附材料已引起了化学家们的极大关注。孔结构分析表明:活性炭纤维的孔径分布窄,孔径比较均匀。本文以活性炭纤维作为去除水中重金属离子Cu2+的吸附剂,吸附实验表明,活性炭纤维对Cu2+的最大吸附量为148.50mg.g-1,吸附平衡时间短,当接触时间为50min时,即可达到吸附平衡,吸附过程符合Langmuir和Freundlich模型。动态吸附结果表明,活性炭纤维对Cu2+的吸附量随着流速的增加而降低。
In recent years, activated carbon fiber （ACF） as a new type activated carbon has aroused enormous interest. The pore structure analysis shows that activated carbon fiber with narrow and homogeneous pore size distributions can be obtained. Activated carbon fiber was used as adsorbent Of Cu^2＋ in water in this paper. Thermodynamic analysis revealed that the adsorption reached to equilibrium in 50 minute and the saturated adsorption amount reached 148.50mg·g^-1 of activated carbon fiber for Cu^2＋. The experimental equilibrium data was fitted to the Langmuir and the Freundlich models. The dynamic adsorption result indicated that the adsorption amount of activated carbon fiber for Cu^2＋ decreased with the increasing of flow rate.
