| 摘 要： | 采用表面印迹技术制备了磁性分子印迹聚合物（Fe3O4@SiO2@MIPs）,使用扫描电镜（SEM）、透射电镜（TEM）和红外光谱（FT-IR）对产物的结构进行了表征。通过吸附性能实验研究证实了制备的Fe3O4@SiO2@MIPs对目标分子2,4-二氯酚（2,4-DCP）具有快速的吸附动力学特征和较高的吸附容量;与非印迹聚合物（Fe3O4@SiO2@NIPs）比较,Fe3O4@SiO2@MIPs对2,4-DCP表现出显著的亲和性;吸附选择性实验表明,Fe3O4@SiO2@MIPs对2,4-DCP具有较强的特异结合性能。此外,5次的重复使用后,制备材料的吸附效率仍可达80%以上,说明该材料具有可重复使用性。

| Abstract: | This paper reports the preparation of magnetic surface-imprinted polymer,Fe3O4@SiO2@MIPs,for separating 2,4-DCP in the environmental water.The structures of the resulting composites were characterized by scanning electron microscopy（SEM）.Transmission electron microscope（TEM）and Fourier transform infrared（FT-IR）analysis.The adsorption experiments of Fe3O4@SiO2@MIPs for 2,4-DCP was demonstrated by equilibrium rebinding experiments,and the results show that the Fe3O4 @SiO2@MIPs have rapid adsorption dynamics process and high adsorption capacity for 2,4-DCP;when compared with the nonimprinted polymer（Fe3O4@SiO2@NIPs）,the Fe3O4@SiO2@MIPs showed outstanding and selective affinity toward 2,4-DCP; the removal efficiency of the Fe3O4@SiO2@MIPs were also above 80%after used five repeated cycles. |
