摘要:

利用聚丙烯腈在碱性条件下水解为含有酰胺基团和羧酸基团的聚电解质的反应,通过控制腈纶丝水解时间和条件,使水解度处于最佳范围内,所得到的水解产物对废水有最佳的处理效果,成为价格低廉,性能优越的混凝剂。

关键词: 聚丙烯腈, 酰胺基团, 羧酸基团, 混凝剂

Abstract:

The polyacrylonitrile is used to form polyacrylamide coagulant under alkaline condition. The coagulant includes amide group and carboxy. Through controlling the reaction condition, we can get hold of the best product which treats wastewater well. And the product is a low-cost and best quality coagulant.

Key words: polyacrylonitrile, amide group, carboxy, coagulant
