The Fe3 O4 modified with silicon was synthesized as carrier material. The core-shell magnetic molecularly imprinted poly-mers( Fe3 O4@SiO2-MIPs) was prepared using monuro as template with surface molecular imprinting technology. The structures of the resulting composites were characterized by scanning electron microscopy( SEM) and vibrating sample magnetometer( VSM) anal-ysis. The adsorbability and selectivity of Fe3 O4@SiO2-MIPs were studied through the static equilibrium biding method. The results showed that compared with magnetic non molecularly imprinted polymers,Fe3 O4@SiO2-MIPs showed higher selectivity and specific adsorption. The maximum adsorption capacity was 80 μmol g-1 . The Scatchard analysis showed that Fe3 O4@SiO2-MIPs existed two different adsorption sites. Langmuir adsorption model can well describe the absorption isothermals of monuro with the correlation co-efficients R2=0. 9989.%以二氧化硅修饰的四氧化三铁为载体,灭草隆为模板分子,采用表面印迹技术制备了核-壳结构的磁性灭草隆分子印迹聚合物( Fe3 O4@SiO2-MIPs)。采用扫描电镜( SEM)和磁强计( VSM)对产物的结构进行了表征。通过静态平衡结合法研究了磁性分子印迹聚合物的吸附能力、选择性。结果表明,与磁性非分子印迹聚合物相比,磁性分子印迹聚合物对灭草隆具有高选择性和高特异性吸附,最大吸附量80μmol g-1；Scatchard 分析表明,印迹聚合物存在两类不同的吸附结合位点,Langmuir模型可以很好拟合吸附等温线,其相关系数R2=0．9989。
