摘要：
A molecularly imprinted polymer was synthesized using 2-(diethylamino) ethylmethacry -late(DEM) and bismethacryloyl-β-cyclodextrin(BMA-β-CD) as bi-functional monomers and norfloxacin(NOF) as a template. The results of equilibrium binding experiments indicated that the polymer has affinity and specificity for NOF in aqueous media, and that its selective recognition ability for the template was higher than that of the imprinted polymers synthesized with a single functional monomer (BMA-β-CD or DEM).
