Abstract: Using coumarin-3-carboxylic acid as template molecule, molecularly imprinted polymer composite membranes with supporting membrane(polyvinylidene fluoride) were prepared through in situ polymerization by UV\|irradiation. The polymer membranes were synthesized by using acrylamide as the hydrogen-bonding monomer and ethyleneglycol dimethacrylate(EDMA) or tris(hydroxymethyl) propane trimethacrylate(TRIM) as cross linker. By comparing adsorption and permeation of the membranes with EDMA or TRIM as cross linker, and different solvents, the imprinted membranes with TRIM as the cross lingker and acetonitrile as solvent showed a higher adsorption capability, and the imprinted membranes with TRIM as the cross lingker and acetonitrile-water(volume ratio 1∶9) as the solvent showed higher permeation selectivity to the template.
