Abstract
An imprinted polymer membrane (IPM) with blending trimethoprim-MIP and polysulfone (PSF) was prepared by bulk polymerization and membrane preparation. In the process of the preparation, the influencing factors on membrane structure and properties, such as the concentration of PSF, the content of additive polyethelene glycol (PEG) and TMP imprinted polymer, were thoroughly investigated by scanning electron microscopy (SEM) and the membrane performance tester. The adsorption properties and selectivity properties of IPM to different substrates were estimated by using the method of equilibrium binding experiments. Finally, the transport properties of the membranes were investigated by using the diffusion chambers. The results showed that the imprinted polymer membrane exhibited a high selectivity for TMP.
