| 摘 要： | 以苯胺和二甲基苯胺为模板分子、甲基丙烯酸(MAA)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,采用悬浮聚合法制备了磁性分子印迹聚合物微球(MMIPMs)。结果表明,改性Fe3O4微粒在MMIPMs中分散较好,MMIPMs在水性介质中对模板分子的选择吸附性较差,但在有机介质中有较好的选择吸附性。

| Abstract: | Magnetic molecularly imprinted polymer microspheres(MMIPMs) were prepared by suspension polymerization,using trimethylolpropane triacrylate(TRIM),methacrylic acid(MAA) and surface modified Fe_3O_4 as crosslinker,functional monomer and magnetic component,respectively.It is found that modified Fe_3O_4 dispersed very well in the prepared magnetic molecularly(imprinted) polymer microspheres.The molecular recognition properties of the MMIPMs for aniline and dimethylaniline in toluene and aqueous ethanol solution were investigated.Results show that the molecular recognition of the MMIPMs in toluene is better than that in aqueous ethanol solution. |
