一种用于处理含重金属离子废水的聚乙烯醇水凝胶及其制备方法
摘要：
本发明涉及一种用于处理含重金属离子废水的聚乙烯醇水凝胶。它是采用包括以下各原料经反应而制备得到：聚乙烯醇，2-丙烯酰胺-2-甲基丙磺酸，不饱和有机酸，N-N亚甲基双丙烯酰胺，引发剂，钠基蒙脱土，丙烯酰氧乙基烷基溴化铵；其中，所述聚乙烯醇聚合度为400～3000，醇解度为75%～99%。本发明中的聚乙烯醇水凝胶具有阴、阳离子的两亲性，可增强其对废水中各种重金属正负离子的处理能力和处理效率，且其制备方法快速、简便。
摘要（英）：

The invention relates to polyvinyl alcohol hydrogel for treating wastewater containing heavy metal ions. The polyvinyl alcohol hydrogel is prepared by polyvinyl alcohol, 2-acrylamide-2-methyl propane sulfonic acid, unsaturated organic acid, N-N methylene bisacrylamide, initiator, sodium montmorillonite and acrylyl ethyoxyl alkyl ammonium bromide through reaction, wherein the polymerization degree of the polyvinyl alcohol is 400-3000, and the alcoholysis degree of the polyvinyl alcohol is 75-99%. The polyvinyl alcohol hydrogel has has the advantages that the polyvinyl alcohol hydrogel has amphipathy of anions and cations, the treatment ability and efficiency of the polyvinyl alcohol hydrogel to various heavy metal cations and anions in the wastewater can be enhanced, and the polyvinyl alcohol hydrogel is fast and simple in preparation method.
