The poly(glycidyl methacrylate) adsorbents P(GMA-EDMA) and P(GMA-DVB) were synthesized by the radical suspension-polymerization method and farther coupled by oligo-beta-cyclodextrin (CDP) to obtain P(GMA-EDMA)-CDP and P(GMA-DVB)-CDP. The synthesized polymeric media were characterized by Fourier transform infrared (FTIR) spectrometer, scanning electron microscopy, and BET surface area. The adsorption of puerarin from aqueous solution onto the four media, i.e., P(GMA-EDMA), P(GMA-DVB), P(GMA-EDMA)-CDP, and P(GMA-DVB)-CDP, was studied. An enhanced adsorption of puerarin apparently presented on grafted media. The interaction between the polymeric media and the puerarin was researched by FTIR. The result shows that the adsorption efficiency on P(GMA-DVB)-CDP driven by multiple weak interactions is much higher than that on P(GMA-EDMA) driven by hydrogen bonding interaction only and on P(GMA-DVB) or P(GMA-EDMA)-CDP driven by two interactions.
