PVA/GA/β-CD纳米纤维的制备及染料吸附性能
Preparation of PVA/GA/β-CD Nanofibers and Its Adsorption of Dyestuff
摘要
Abstract
The polyvinylalcohol/β-cyclodextrin(PVA/β-CD) nanofibers with 70%(mass fraction) of β-CD were obtained by electrostatic spinning with hexafluoroisopropanol(HFIP) and H2O as solvents.And after cross-linking treatment with glutaraldehyde(GA), a water-insoluble nanofiber membrane of PVA/GA/β-CD was prepared.Compared with the products before being cross-linking, composition and morphology for the nanofibers were studied by Infrared spectroscopy and scanning electron microscopy.In addition, the adsorptive properties of the PVA/GA/β-CD nanofibers to seven water-soluble dyes were investigated.The results show that the adsorptive effect of fiber on malachite green, methyl violet and congo red are better than others, and the maximum adsorptive capacities are 124.71, 121.14 and 127.39 mg/g, respectively.After four cycles of adsorption-desorption, the dye removal rate still remains 80%.Thus, the nanofiber exhibits an excellent {applicative} prospect in waste water treatment with dye.关键词
