Abstract: The bensulfuron-methyl molecularly imprinted polymers (MIP) were prepared via a UV-initiated precipitation polymerization method at 20 degrees C temperature using bensulfuron-methyl (BSM) as the template molecule, alpha-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 H-1 NMR; the cooperative hydrogen energies (-28.6163 kJ/mol) and the double hydrogen length (0.179 similar to 0.181 min) between the bensulfuron-methyl and alpha-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
