| 摘 要： | 以镁铝双金属离子低聚物为交联剂,制备了复合联膨润土,用于处理含锌废水。通过改变废水溶液pH值、吸附剂用量和搅拌处理时间等因素研究了镁铝交联膨润土对废水溶液中锌的吸附特性和处理效果。研究表明,镁铝交联膨润土对废水中锌的去除效果较好,去除率可以达到99%以上。此外,还对镁铝交联膨润土与膨润土原土的处理效果进行了比较。结果表明,用镁铝交联剂对膨润土进行改性后吸附能力显著增强。

| Abstract: | Using magnesium-aluminum bimetal ion low polymer as crosslinking agent,the magnesum-aluminum cross-linked bentonite was prepared for treating the wastewater containing zinc.The absorptive characteristics and treatment effect of the new product were studied by changing certain factors,such as the pH value,time and so on.The result shows that the absorption ability is well,removal rate of zinc ion can reach above 99%. |
