Molecularly Imprinted Polymer Prepared by Precipitation Polymerization for Quercetin

Abstract

In this paper, molecular imprinted polymer for quercetin was synthesized by precipitation polymerization with acrylamide as functional monomer, ethylene glycol dimethacrylate as cross-linker, 2,2-azobisisobutyronitrile as initiator and acetone as the solvent. The polymers’ adsorption properties were characterized. As results shown that the synthesized imprinted polymer is microspheres with particle size in the nanometer scale, the adsorption capacity of quercetin imprinted polymers is 1.1×10-5mol/g, adsorption temperature is 60°C, adsorption time is 30 min. The molecular imprinting technology was introduced in interference test with a satisfactory result in selectivity.
