Abstract

Salicylic acid complex imprinted polymeric membranes have been prepared by thermal polymerization using polyvinilidene fluoride membrane as a support membrane, acrylamide as a functional monomer and ethylene glycol dimethacrylate as a crosslinker. The imprinted membranes are characterized by Fourier Transform Infrared Spectrometer (FT-IR), thermogravimetric analysis (TGA) and scanning electron microscope (SEM). It can be found that the structure of imprinted membranes is different from the supporting membrane, and the surface of the supporting membrane is covered with an imprinted polymer layer after polymerization. Adsorption and permeation binding experiments indicate that imprinted membranes show high specific binding capacity of template molecule, the selectivity factor of the imprinted membrane for the salicylic acid was 26.4, The optimum polymerization condition is 0.3 mmol salicylic acid, 1.2 mmol acrylamide and 6.0 mmol ethylene glycol dimethacrylate in acetonitrile at 60℃ for 24 h.
