摘要
主要讨论以甲醛和亚硫酸氢钠为磺甲基化试剂对聚丙烯酰胺进行磺甲基化改性,论述了改性树脂对铅离子和铜离子的最佳吸附条件。通过傅立叶红外(FTIR)对磺甲基化改性树脂进行分析,并用扫描电镜(SEM)对树脂吸附重金属离子的形貌进行表征。
This paper mainly discusses the sulfomethylate reaction of polyacrylamide using formaldehyde and sodium hydrosulfite as modifing reagent, studied the condition which was the best result of adsorbing Cu^2+ and Pb^2+. Modified resin was analyzed by FTIR and the adsorptive structure of the resin was characterized by SEM.
