Abstract：Using paracetamol as template molecule, molecularly imprinted polymer membranes with supporting membrane were synthesized through in situ polymerization by UV irradiation. The interaction between template and functional monomer was proved by UV spectrophotometry and based on the results, appropriate reaction solvent was selected. The membrane structure and surface features were analyzed by FT-IR and scan electron micrography. Permeation experiment showed that permeation solvent greatly influenced the permeation result. Appropriate solvent could increase the permeation selectivity of the imprinted membrane for the template.
