静电纺丝技术制备Na2EDTA/PVDF纤维膜及去除Cu2+的应用研究OA
该文采用静电纺丝技术制备乙二胺四乙酸二钠(Na2EDTA)/聚偏氟乙烯(PVDF)复合纤维膜,系统研究 PVDF 和Na2EDTA 含量对纤维膜形貌和性能的影响.通过紫外-可见吸收光谱法测试纤维膜的吸附性能,并使用扫描电子显微镜(SEM)、傅里叶变换红外光谱(FTIR)和能量散射 X 射线光谱(EDS)对吸附前后的纤维膜进行表征.结果表明,当 PVDF 的质量分数为 12%、Na2EDTA 的含量为 0.06 g/mL 时,所制备的 Na2EDTA/PVDF 纤维膜表现出优良的综合性能.在 1.596 2 mg/L 铜离子溶液中,Na2EDTA/PVDF纤维膜的吸附率达到 45.24%.
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%.
