Abstract: L-Phe molecularly imprinted polymers were prepared in three methods, which are the conventional bulk polymerization, emulsion polymerization and polymerization with silica gel as sacrificial materials. In the polymerization procedure, L-Phe was selected as the template molecule, α-methacrylic acid and 4-vinyl pyridine as the functional monomers, glycol dimethacrylate and 1,4-divinylbenzene as the crosslinkers, dimethyl sulfoxide as the solvent with proper proportion. The specific surface area and the pore volume of MIPs and the particle size distribution were examined through Brunauer-Emett-Teller method of nitrogen adsorption (B.E.T.) experiments and with laser granularity distribution apparatus. Under the same condition, MIPs prepared with silica gel as the sacrificial material show the most amount of specific surface area (273 m2/g). The most amount of saturated adsorption (33.89 mg/g) can also be obtained in the method with silica gel as the sacrificial material. The values of the static separating coefficient and the dynamic separating factor are 1.68 and 1.227 respectively
