摘　　要：设计了一个可以将分析化学、无机化学、有机化学及物理化学集于一体的综合性实验。该实验首先可控合成具有三维孔道结构的ZSM-5分子筛,再运用X射线衍射、扫描电子显微镜及物理吸附对其结构、形貌和孔径分别进行表征;继而考察改变pH、吸附时间、吸附温度、ZSM-5使用量等因素对水中Cu2+吸附性能的影响。本实验涉及无机化学、有机化学中的合成理论知识,物理化学的表面吸附原理,分析化学中的数据处理方法及大型仪器的使用。在锻炼了学生动手操作能力的基础上,又提高了学生对实验结果进行分析、评价的综合能力。This paper designed a comprehensive experiment including analytical chemistry, inorganic chemistry,organic chemistry,and physical chemistry.Firstly,this experiment prepared ZSM-5 zeolite which was characterized by X-ray diffraction (XRD),scanning electron microscope (SEM),and physical adsorption.The change of ZSM-5 in experiment was quantitatively correlated with the structure,surface topography and pores size distribution.Thereafter,the effect of pH,adsorption time,adsorption temperature,and ZSM-5 content on the adsorption of Cu^2+ was studied.This experiment involved the synthesis theory of inorganic and organic chemistry,the surface adsorption principle in physical chemistry and the application of analysis methods of analytical chemistry.Meanwhile,the use of data processing methods and large-scale instruments could not only exercise the practical operating ability for students,but also improve the ability to analyze the experimental data and results evaluation for students.
