淀粉接枝聚丙烯酰胺阳离子絮凝剂的合成及应用——推荐一个高分子化学综合实验

doi:10.3866/PKU.DXHX202109020

Abstract

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
