摘要

以2

4-二氯苯氧乙酸（2

4-D)为模板分子，甲基丙烯酸(MAA)为功能单体，Fe

为磁性载体，采用乳液聚合方法制备了相应的磁性分子印迹聚合物（Mag-MIPs）。采用透射电镜（TEM）、热重分析（TG）等对Mag-MIPs进行了一系列表征。吸附实验表明该磁性印迹聚合物对2

4-D的吸附能力明显强于非印迹聚合物。采用MagMIPs为固相萃取材料，结合高效液相色谱分析，对质量浓度约为50 μg·L

Abstract

In this work

the magnetic molecularly imprinted polymers (Mag-MIPs) based on Fe

magnetite were prepared using 2

4-dichlorophenoxyacetic acid (2

4-D) as a template molecule. The morphological and magnetic characteristics of the Mag-MIPs were characterized by transmission electron microscopy (TEM)

fourier transform infrared spectrometer (FT-IR)

and vibrating sample magnetometry (VSM). The specific adsorption property was studied using binding experiment. The result showed that Mag-MIPs had higher recognition for the template than the nonimprinted polymers (MagNIPs). Moreover

the specific recognition of Mag-MIPs was further investigated using solid phase extraction (SPE) coulped high performance liquid chromatography (HPLC) analysis of the simulation water samples. The maximum recoveries of spiked sample were in range of 91.7%~110.4% with RSD 7.38 (n=3). These results indicate that magMIPs has potential application in separation and analysis of biological and environmental sample.
