摘要：

介绍一个综合化学实验。实验通过淀粉与丙烯酰胺的接枝聚合反应和阳离子化改性，合成了一种新型淀粉接枝聚丙烯酰胺阳离子高分子絮凝剂，进行了结构表征，以人工模拟染料废水和重金属离子废水为实验对象，探究了合成的聚丙烯酰胺、淀粉接枝聚丙烯酰胺和淀粉接枝聚丙烯酰胺阳离子絮凝剂在废水净化中的应用。本实验理论与实践相结合，有助于激发学生的学习兴趣，培养学生的学科交叉融合思维和分析解决问题的能力。

Abstract:

A comprehensive chemical experiment is introduced. A new cationic polymer flocculant of starch grafted polyacrylamide was synthesized by graft polymerization and cationic modification. The structure was characterized and the application of polyacrylamide, starch grafted polyacrylamide and starch grafted polyacrylamide cationic flocculants in wastewater purification was investigated. This comprehensive experiment combines theory with practice, which helps to stimulate students' interest in learning, cultivate students' interdisciplinary thinking and the comprehensive ability to analyze and solve practical problems.

Key words: Starch, Polyacrylamide, Flocculant, Comprehensive experiment, Waste water
