Abstract

Fe3O4 magnetic nanoparticles were prepared by coprecipitation method and coated with SiO2 via a sol-gel process, then a magnetic molecularly imprinted polymers (Fe3O4—MIPS) of bisphenol A were prepared by emulsion polymerization using BPA as template, α-methacrylicas as functional monomer,divinylbenzene as cross-linker, azobisobutyronitrile as initior. The Fe3O4—MIPS were characterized by Fourier transform infrared spectroscopy (FT—IR),Transmission electron microscopy(TEM) and Sample vibrating magnetometry(VSM) in order to elucidate the morphology, magnetic and other properties, the results showed that they possessed uniform distribution of particle size, which was about 15 nm, and with a good magnetic property.The results of adsorption experiment indicated that the Fe3O4—MIPS have a much higher adsorbability than Fe3O4—MNIPS, and it had a high selective adsorption for BPA, the Scatchard analysis results demonstrate that the maximum apparent adsorption quantity of BPA was 126.44 μmol/g.
