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%.
