Synthesis of α-, β- and γ-Cyclodextrin/ Poly(Acrylonitrile) Composite Nanofibers and Their Applications to Cu(II) Ion Adsorption

A novel adsorption material of α-, β- and γ-cyclodextrin (CD)/ Poly(acrylonitrile) (PAN) composite nanofibers was prepared via electrospinning. The PAN composite nanofibers were applied to Cu (II) ion adsorption, which is suitable for Cu (II) ion adsorption due to their high adsorption affinity for metal ions. The amounts of the metal ions adsorbed onto α-, β- and γ-CD/PAN composite nanofibers mats were influenced by α-, β- and γ-CD concentration and the contact time. The physicochemical properties and adsorption performance of α-, β- and γ-CD/PAN composite nanofibers were characterized.
