磁性分子印迹聚合物对石榴皮中白藜芦醇的选择性富集
Magnetic Molecularly Imprinted Polymer for Selective Enrichment of Resveratrol in Pomegranate Rind
摘要
Abstract
Fe3O4 magnetic molecularly imprinted polymers(Fe3O4@MIPs)were prepared by adopting surface molecular imprinting technology using Fe3O4 particles as the magnetic core,resveratrol as the template molecule,and dopamine(DA)as the functional monomer and crosslinking agent.The surface groups,particle shape,skeleton structure,and magnetization intensity of Fe3O4@MIPs were characterized through scanning electron microscopy(SEM),infrared(IR)spectroscopy,X-ray diffraction(XRD)and vibrating sample magnetometry(VSM),and its adsorption performance for resveratrol was detected using high performance liquid chromatography(HPLC).The results indicated that Fe3O4@MIPs had high magnetization intensity and showed a stable morphology.When the adsorption time was 150 minutes and the concentration of resveratrol was 40 μg/mL,the maximum adsorption capacity of 35.101 μg/mg was obtained,indicating a good adsorption performance.In conclusion,solid phase extraction with Fe3O4@MIPs as the sorbent enabled selective recognition and enrichment of resveratrol from pomegranate rind.关键词
