The bensulfuron-methyl molecularly imprinted polymers (MIP) were prepared via a UV-initiated precipitation polymerization method at 20 ℃ temperature using bensulfuron-methyl (BSM) as the template molecule, α-methacrylic acid (MAA) as the functional monomer, trimethylolpropane trimethacrylate (TRIM) as the cross-linker and dichloromethane as the porogen. The cooperative hydrogen bonds of the pre-polymerization solution between the template molecule and the functional monomer were evaluated by UV-spectrum and 1H NMR; the cooperative hydrogen energies (-28.6163 kJ/mol) and the double hydrogen length (0.179~0.181 nm) between the bensulfuron-methyl and α-methacrylic acid were calculated through Hyperchem 7.0 and Gaussian 03W software. The MIP shows high binding capacity to the BSM with HPLC and adsorption kinetics experiments.

Key words: bensulfuron-methyl, molecularly imprinted polymer, sulfonylurea-herbicide molecular simulation
