摘要:

介绍一个物理化学综合实验。本实验以制备的有序介孔二氧化硅MCM-41为吸附剂,研究了水溶液中亚甲基蓝在其表面的吸附性能。通过利用Langmuir和Freundlich吸附等温式对吸附数据进行分析、处理和拟合。本综合实验教学不仅促进学生对材料结构与性能的认识,而且加强了学生对固体表面吸附过程的理解。

Abstract:

This study reports a comprehensive physical chemistry experiment including MCM-41 synthesis, characterization and adsorption performance. The adsorption processes of methylene blue on MCM-41were measured and analyzed according to Langmuir and Freundlich adsorption isotherms. This comprehensive experiment could help the students understand the structure-property relationship and adsorption processes on solid surfaces.

Key words: MCM-41, Physical chemistry, Methylene blue, Adsorption
