Study on Preparation and Recognition Properties of Quercetin Molecularly Imprinted Polymers
Molecularly imprinted polymers (MIPs) are a class of highly cross-linked polymers that have high selectivity and affinity for the target molecule.In this study bulk polymerization was employed to prepare the MIPs,which used quercetin (QUE) as the template molecule and ethylene glycol dimethacrylate (EDMA) as the cross-linker.The influence of three synthetic conditions,including functional monomer (AM,2-VP,4-VP,MAA),porogen (THM,ACE,THM/DMF) and reactant ratio of n (QUE): n (4-VP): n (EDMA),were investigated.The synthesized polymers were analyzed by infrared spectroscopy and scanning electron microscope.The dynamic curves and adsorption isotherms were used to evaluate the adsorption properties of the synthesized polymers as well.The experimental results show that the best functional monomer was 4-vinyl pyridine (4-VP),reactant ratio of n (QUE): n (4-VP): n (EDMA) = 1:5:25 was better than others ratio,the best porogen was blend solvent of THM/DMF (5.5: 1.5 V/V).Under the optimum condition,the equilibrium adsorption and the selectivity coefficient (a = 3.58) of QUE-MIP7 were obviously higher than these of NIP.
