摘要：采用沉淀聚合法,以Fe_(3)O_(4)纳米颗粒为载体,1,2,3,4,6-五没食子酰葡萄糖(PGG)为模板分子,丙烯酰胺(AM)为功能单体,制备了PGG磁性分子印迹聚合物(MIPS)和磁性非印迹聚合物(NIPS,不加PGG),表征了其形貌和结构,并考察了其对PGG的吸附性能。SEM、TEM、FT-IR和XRD分析结果表明:MIPS是以Fe_(3)O_(4)为核心的外层包有SiO_(2),表面密布孔穴的球形纳米颗粒。磁学性质分析发现:MIPS具有良好的顺磁性,在外加磁场下能够实现分离。吸附性能研究结果表明:MIPS对PGG的吸附能力明显强于NIPS,MIPS对PGG的吸附过程比较符合Langmuir等温吸附模型,最大吸附量为67.02 mg/g,MIPS对PGG的吸附过程非常符合准二级动力学模型。在MIPS的重复利用性能实验中,其吸附第5次的吸附量为53.16 mg/g,仍能达到第1次使用时的吸附量的83.78%,表明MIPS的重复使用性能较好。
The magnetic molecularly imprinted polymers(MIPS) and magnetic non-imprinted polymers(NIPS,without PGG) were prepared by precipitation polymerization using Fe_(3)O_(4) magnetic nanoparticles as carriers,1,2,3,4,6-penta-galloyl glucose(PGG) as template molecule and acrylamide(AM) as functional monomer.Their morphology and structure were characterized,and the adsorption performance was investigated.The results of SEM,TEM,FT-IR,and XRD showed that MIPS was spherical nanoparticle with Fe_(3)O_(4) as the core and SiO_(2) as the outer layer,with densely packed pores on the surface.The analysis of magnetic properties shows that MIPS has good paramagnetism and can be separated under applied magnetic field.The results show that the adsorption capacity of MIPS for PGG is obviously stronger than that of NIPS.The adsorption process of PGG by MIPS was fitted well with the Langmuir adsorption isotherm model,with a maximum adsorption capacity of 67.02 mg/g.The adsorption process of PGG by MIPS was very consistent with the second-order kinetic model.In the reuse performance experiment of MIPS,the adsorption capacity of the fifth cycle 53.16 mg/g,could still reach 83.78% of the first adsorption capacity.This indicated that the reuse performance of MIPS was better and could achieve specific adsorption of PGG.
