| 摘 要： | 以废弃聚乙烯(PE)塑料与具有亲水性基团的丙烯酸(AA)及其盐接枝共聚合成一种高吸水性树脂,并将所得高吸水树脂用于溶液中Cu2+的吸附。通过分光光度法研究了树脂去除水溶液中Cu2+的情况,考察了起始pH、树脂用量、金属离子起始浓度和吸附时间对金属离子去除率的影响。结果表明,该树脂对Cu2+具有较强的吸附性能。树脂初期吸附速率大,吸附达到平衡时的接触时间为30 min。当溶液pH为7.0,Cu2+初始浓度为25 mg/L,树脂用量在8 g/L时,树脂对Cu2+的去除率可达95.0%以上。

| Abstract: | The superabsorbent was prepared from waste plastics and acrylic acid(AA) by polymerization.The adsorption of the superabsorbent to Cu2+ was studied.The results have shown that the resin has a good adsorption to Cu2+.The adsorption of copper ions on the resin differed greatly at different pH values,initial concentrations of Cu2+ and concentrations of resin.The adsorbing equilibriums are reached within 30 minutes.When pH is about 7.0,the initial concentration of Cu2+ is 25 mg/L in the solution,and the concentration of resin is 8 g/L,the removal rate of Cu2+ is up to 95.0%. |
