摘要
通过一步法静电纺丝制备聚丙烯腈复合MIL101(Fe)纳米纤维膜,原位将MIL101(Fe)结合到聚丙烯腈纳米纤维中,MIL101(Fe)的结晶和聚合物固化在静电纺丝过程中同时发生。红外光谱、EDS能谱和XRD表征证实,MIL101(Fe)晶体有效均匀地结合在聚丙烯腈纳米纤维中且结晶度良好、分布均匀。得益于MIL101(Fe)晶体和聚丙烯腈的协同作用,PAN-MIL101(Fe)复合纳米纤维对有机离子染料表现出快速的去除速率。该研究为快速去除废水中的有机离子染料提供了参考。
PAN-MIL101(Fe) composite nanofiber membranes were prepared by one-step electrospinning. MIL101(Fe) was bonded to polyacrylonitrile nanofibers. Crystallization and polymer solidification of MIL101(Fe) occurred simultaneously during electrospinning. The results of FT-IR, EDS and XRD showed that MIL101(Fe) crystals were effectively and uniformly bonded in polyacrylonitrile nanofibers with good crystallinity and uniform distribution. Due to the synergistic effect of MIL101(Fe) crystal and polyacrylonitrile, PAN-MIL101(Fe) composite nanofiber membrane showed a fast adsorption rate for organic ionic dyes. This research provides a new idea for electrospinning MOF-based nanofiber membrane as a filter for rapid separation and purification of organic dyes in practical wastewater.
