英文摘要: A molecularly imprinted polymer(MIP) was prepared with N-(4-isopropylphenyl)-N'-butyleneurea as a template and MAA as a functional monomer and EDMA as a cross-linker. The affinities and selectivities of the MIP for phenylurea herbicides were studied. Among the fourteen phenylurea herbicides tested, the MIP prepared shows obviously high affinities and selectivities for ten chemicals (monuron, diuron, isoproturon, fenuron, chlortoluron, difenoxuron, metoxuron, neburon, buturon and fluometurion) with dichloromethane as the mobile phase while the non-imprinted polymer shows very low affinities for all the phenylurea herbicides tested. Recognition mechanism was also discussed. The results of the experiments and Mulliken atomic charges calculated indicate that the recognition site is mainly located at the N' position of phenylurea herbicides.
