Glycylglycine molecular imprinted polymer microspheres were prepared by emulsion polymerization in the aqueous phase at low temperature with Gly-Gly as template,acrylamide as functional monomer and ethylene glycol dimethacrylate as crosslinker.The selective adsorption ability of Gly-Gly-MIPMs was detected by static,dynamic equilibrium adsorption experiments and the TLC separation tests,and the selective binding characteristics were evaluated with Scatchard analysis.The results revealed that Gly-Gly-MIPMs possessed specific molecule recognition ability,the maximum apparent adsorption amount was 0.428mmol/g and the imprinting factor reached 2.19.
