摘　　要：腈纶废丝在常压碱性条件下水解后,与二甲胺进行接枝制备絮凝剂的适宜条件为:NaOH、水、二甲胺用量分别为14 g、160 mL、36 g,接枝温度为90℃,在此条件下制得的絮凝剂对废水的除浊效果可达到92%以上。Flocculant was prepared by the acrylic waste silk and dimethylamine with hydrolysis reaction. Under the atmospheric alkaline condition. The result showed that the optimal conditions is the effect of removal turbidity could surpass 92% by small amount when the NaOH is 14 g,H2O is 160 mL, （CH3）2NH is 36 g, the temperature of reaction is 90 ℃.
