| 摘 要： | 以二氯苯酚为模板分子、丙烯酰胺(AM)为功能单体、三羟甲基丙烷三丙烯酸酯(TRIM)为交联单体、Fe3O4为磁性组分,采用反相微乳液悬浮聚合法制备了磁性分子印迹聚合物微球(MMIPMs)。研究了吸附时间、温度、pH对吸附性能的影响,并考察了其重复利用性。结果表明,温度对二氯苯酚-MMIPMs吸附性能影响不大。底物溶液pH对MMIPMs的吸附性能有一定影响,吸附量随pH的升高而增大,当pH为7.0时,吸附量最大。MMIPMs具有良好的重复利用率。

| Abstract: | Magnetic molecularly imprinted polymer microsp heres（MMIPMs） were prepared by inverse micro-emuldion suspension polymerization,using dichlorphenol,trimethylolpropane triacrylate（TRIM）,acrylamide（AM） and surface modified Fe3O4 as template molecule,crosslinker,functional monomer and magnetic component,respectively.The influence of adsorption time,temperature and pH on the adsorptivity of MMIPMs were investigated,the reuse rate was also tested.The results showed that the influence of temperature on the adsorptivity of dichlorobenzene phenol-MIPMs was not obvious.The pH of substrate solution had some influence to the adsorption quantity of MMIPMs,which increased with pH increasing.The largest adsorptive capacity was obtained when pH was 7.MMIPMs had good reuse rate. |
