摘　　要：介绍了一个研究型综合实验,涉及镉配位聚合物的合成及其染料吸附性能研究。该实验使用常见有机配体丁二酸、1,4-二(1-咪唑)苯与硝酸镉四水合物,在溶剂热条件下进行反应得到一例镉配位聚合物。利用X射线单晶衍射、X射线粉末衍射、热重分析、红外光谱对配位聚合物进行结构表征,并对其染料吸附性能进行研究。该实验将科学研究热点融入基础实验教学,既巩固了学生的基础理论知识,提高了实验技能,又拓展了学生的科学视野,加强了他们独立分析问题、解决问题的能力,有利于培养学生的创新精神和实践能力。A comprehensive research experiment involving the synthesis of a cadmium coordination polymer and its dye adsorption properties was introduced. The cadmium coordination polymer was synthesized from succinic acid, 1,4-bis(1 H-imidazol-4-yl)benzene and cadmium nitrate tetrahydrate under solvothermal conditions. The structure of the coordination polymer was characterized by X-ray single crystal diffraction, X-ray powder diffraction, thermogravimetric analysis, infrared spectroscopy, and its dye adsorption properties were also studied. The experiment integrates scientific research hotspots into basic experimental teaching, which not only consolidates students’ basic theoretical knowledge and improves their experimental skills, but also broadens students’ scientific horizons, strengthens their ability to analyze and solve problems independently. It is conducive to cultivating students’ innovative spirit and practical ability.
