In this paper, using environmental hormone dibutyl
phthalate (DBP) in the contaminated foods as the template molecule, methacrylic acid (MAA) as
functional monomer, ethylene glycol dimethacrylate ester (EDMA) as cross linking agent, the
molecularly imprinted polymer (MIP) was prepared on the silica surface. The MIP was characterized
by Fourier transform infrared spectroscopy (FTIR), thermogravimeric analysis (TGA) and automated
surface area analyzer. The property of adsorption was tested using static adsorption method in
water phrase. The results of FTIR indicate that there are recognition groups in the microspheres
after imprinting. TGA illustrates the silica gel surface has been coated with a layer of polymer
after the synthesis reaction. And the MIP can bear the high temperature of 200 degrees C. The
thickness of the imprinted polymer coated on silica gel surface is estimated via the pore size
data is about 1.5nm. The result of static adsorption experiment shows that the saturated
adsorption capacity of the MIP was 8.940mg/g.
