Abstract Three molecularly imprinted polymers were synthesized with different functional monomers respectively, using methyl parathion as the template. These monomers are methacrylic acid, acrylamide and 4-vinylpyridine. According to the UV spectrum study the interaction between methyl parathion and 4-vinylpyridine was stronger than that of the others. Comparably, the infrared spectrum study showed the same results which indicated that 4-vinylpyridine could associate with the template at two different kinds of binding sites, the P—O—C and the —NO2 site, and is most likely to form steady covalent bonds with methyl parathion, while the other two monomers could only associate with the template at the P—O—C site. Furthermore, the infrared spectra of the synthesized polymers confirmed the existence of the functional groups in each kind of polymer, which might interact with the template.
