Waste organic dye removal using MOF-based electrospun nanofibers of high amine density

The exceptional structural stability of UiO-66 metal–organic framework (MOF) and ligands' functional groups render as a versatile candidate for multiple applications, including wastewater treatment. possibility broad spectrum post-synthetic modification further expands its prospective uses. However, commercial applications have been hindered by the polycrystalline nature powder. In this research, to obtain UiO-66-NH2 post-processing with nanofibers comprising chitosan polyvinyl alcohol (PVA) were applied faciliate deployment suitable option water decontamination. MOF nanoparticles post-synthetically modified 2,4,6-trichloro-1,3,5-triazine (TCT) 5-phenyl-tetrazole (PT) produce high-amine containing UiO-66, thus introducing active nitrogen-containing that enhanced removal efficiency targeted molecules from aqueous media. A systematic study was undertaken optimize supporting demonstrate even low functionalization, up 7- wt%, offered maximum methyl orange adsorption capacity 619 mg/g, superior most adsorbents reported so far. Furthermore, selectivity, regeneration ability, effect ambient conditions demonstrated.
