主　　题：cyclodextrin metal-organic framework graphene oxide membrane filter naringin enrichment 

摘      要：A green,renewable composite was designed and fabricated based on self-assembly of cyclodextrin metal-organic framework(CD-MOF)on graphene oxide(GO).Then,the GO@CD-MOF was embedded in 0.45μm PTFE membrane to produce a dual-functional membrane which could carry out sample enrichment by capturing naringin molecules.The membrane filter was further improved by investigating the effects of the experimental parameters including amount of GO@CD-MOF,enrichment time and elution solvent on enrichment efficiency of naringin.Further,the present method had been successfully applied to citrus sample and obtained satisfied recovery value(79.7%-100.3%).Moreover,the extraction of naringin can be achieved for 2 min,and GO@CD-MOF loaded membrane can be reused at least for 5 times.The results demonstrate that the fabrication of the novel filter membrane based on GO@CD-MOF is a fast,simple and reliable,and possesses great potential in the determination of naringin from real samples by dual-function of separation and enrichment.
