静电纺丝技术制备Na2EDTA/PVDF纤维膜及去除Cu2+的应用研究
摘要
Abstract
This study employed electrospinning technology to prepare disodium ethylenediamine tetraacetate(Na2EDTA)/polyvinylidene fluoride(PVDF)composite fiber membranes.The effects of PVDF and Na2EDTA content on the morphology and properties of the fiber membranes were systematically investigated.The adsorption performance of the fiber membranes was tested using ultraviolet-visible(UV-Vis)absorption spectroscopy,and the membranes before and after adsorption were characterized by scanning electron microscopy(SEM),Fourier-transform infrared spectroscopy(FTIR),and energy-dispersive X-ray spectroscopy(EDS).The results indicated that when the mass fraction of PVDF was 12%and the concentration of Na2EDTA was 0.06 g/mL,the prepared Na2EDTA/PVDF fiber membranes exhibited excellent overall performance.In a copper ion solution with a concentration of 1.596 2 mg/L,the adsorption rate of the Na2EDTA/PVDF fiber membranes reached 45.24%.关键词
