| 摘 要： | 采用离子交换法制得载铜蒙脱石，研究蒙脱石和载铜蒙脱石对亚甲基蓝（MB）的吸附性能，结果表明载铜蒙脱石的吸附能力低于蒙脱石。温度、介质pH值和离子强度对吸附剂的吸附性能有不同程度的影响；蒙脱石和载铜蒙脱石吸附MB等温线较好地符合BET和Langmuir等温方程，其吸附过程均为热力学自发过程。

| Abstract: | Cu~(2+)-carrier montmorillonite (CEM) was prepared by using the method of ion exchange reaction. The work dealt with the adsorption of methylene blue (MB) on montmorillonite and CEM. The results showed that treatment with Cu~(2+) would slightly reduce the adsorption capacity of montmorillonite. Temperature, pH and ionic strength in the medium had more or less effects on interaction between MB and clay. The isotherms for adsorption of MB on the surfaces of all the four adsorbents were fitted with the Langmuir and BET equations. Also, the adsorption processes were spontaneous with respect to thermodynamics. |
