摘要:

以二氧化硅包覆的四氧化三铁为载体, 双酚A(BPA)为模板分子, β-环糊精和4-乙烯基吡啶为二元功能单体, 采用热聚合方法制备了对双酚A具有特异吸附性能的磁性印迹复合材料(mag-MIPs). 采用透射电子显微镜(TEM)、 傅里叶变换红外光谱(FTIR)和振动样品磁强计(VSM)对该印迹复合材料进行了表征, 并结合磁固相萃取(M-SPE) 技术和高效液相色谱(HPLC)研究了其对双酚A的吸附行为, 结果表明该印迹复合材料对双酚A具有良好的选择吸附能力. 液相色谱检测结果表明, 该磁性印迹复合材料可用于环境水样中双酚A的快速分离富集, 回收率为90.51%~98.21%.

Abstract:

A kind of magnetic molecularly imprinted polymers(mag-MIPs) was synthesized by heated polymerization technique using bisphenol A(BPA) as template, β-cyclodextrin(β-CD) and 4-vinylpyridine(4-VP) as the binary functional monomers. The mag-MIPs were characterized by means of transmission electron microscopy(TEM), Fourier transform infrared spectroscopy(FTIR) and vibrating sample magnetometer(VSM). Adsorption experiments indicated that the mag-MIPs prepared with β-CD and 4-VP exhibited high selectivity toward BPA. The performance of the mag-MIPs used as magnetic solid-phase extraction(M-SPE) sorbent was evaluated, and the results showed that it could selectively extract BPA from water samples. The imprinted magnetic solid-phase extraction method has been applied for preconcentration and purification of BPA from water samples with the recoveries range of 90.51%—98.21%.

Key words: Magnetic molecularly imprinted, Bisphenol A, High-performance liquid chromatography, Solid phase extraction
