Abstract:

In the reaction process of copolymerization of monomers,2-acrylamido-2-methylpropane sulfonic acid(AMPS) and acrylamide(AM),by putting in oleic acid-modified Fe₃O₄ particles,a new type of anionic composite magnetic coagulant AMF has been synthesized. The analysis shows that Fe₃O₄ particles in form of magnetic cores are evenly dispersed in AMF,in which Fe₃O₄,oleic acid,AMPS and AM characteristic absorption peaks are contained. The organic matter content is 70%. The results of coagulation sedimentation tests show that compared with anionic polyacrylamide(APAM) and poly aluminium chloride(PAC),AMF has higher turbidity removing rate in short sedimentation time.

摘要：

在2-丙烯酰胺-2-甲基丙磺酸（AMPS）和丙烯酰胺（AM）单体共聚反应过程中，引入经过油酸改性的Fe₃O₄颗粒，合成一种新型阴离子复合磁絮凝剂AMF。分析表明，Fe₃O₄以磁核的形式均匀地分散在AMF中，且AMF中含有Fe₃O₄、油酸、AMPS和AM特征吸收峰，有机物含量为70%。混凝沉淀试验结果表明，相对于阴离子型聚丙烯酰胺（APAM）和聚合氯化铝（PAC），AMF在较短的沉淀时间内取得了较高的浊度去除率。
