In order to prepare the solid phase extraction column for the effective separation and enrichment of quercetin in the medicinal herb,a novel surface molecularly imprinted polymer was synthesized by a reversible addition fragmentation chain transfer(RAFT) polymerization method,combining molecular imprinting with living radical polymerization techniques,using acrylamide(AM) modified multi walled carbon nanotubes(MWCNTs) as supporting matrix,dibenzyltrithiocarbonate(DBTTC) as reversible RAFT reagent,quercetin as template molecule,methacrylic acid(MAA as functional monomer and acetonitrile as pore former.The multi walled carbon nanotubes molecularly imprinted polymers were characterized by Fourier transform infrared spectroscopy(FTIR),scanning electronic microscopy(SEM) and thermogravimetric analysis(TG).The adsorption properties and specific recognition ability of the polymer were tested by HPLC.The results showed that a stable imprinted layer was successfully grafted on the MWCNTs surface.And the imprinted polymers with good morphology and adsorption property have a specific recognition ability for quercetin.
