摘要
絮凝法是最重要的水污染控制方法之一。絮凝剂是絮凝污染控制方法的关键部分和核心基础,对最终的水处理效果起着至关重要的影响。其中,阳离子聚丙烯酰胺是一类重要的水处理剂,在水处理领域一直备受关注。综述了阳离子聚丙烯酰胺自由基共聚合法的引发体系与研究进展,主要介绍了偶氮类引发体系、氧化还原引发体系、复合引发体系和紫外光引发体系的特点和应用,阐述了阳离子聚丙烯酰胺中常用的共聚阳离子单体的种类和应用,对阳离子聚丙烯酰胺未来的发展趋势和研究方向进行了展望。
Flocculation is one of the most important water pollution control methods.Flocculant is a key foundation of flocculation pollution control method,which plays a vital role in the final water treatment effect.Among these,cationic polyacrylamide is an important type of water treatment agent,which has been of concern in the field of water treatment.The initiation system in the free radical copolymerization and research progress of cationic polyacrylamide are summarized.Characteristics and application of initiation system in the polymerization,such as azo-initiator system,redox initiation system,complex initiation system and UV initiation system are introduced mainly.The types and application of common cationic monomers in the copolymerization are elaborated.Furthermore,its future development tendency and research direction are predicted.
