Improving ofloxacin removal and antifouling performances of polysulfone-based mixed matrix membranes using chitosan-grafted UiO-66-NH2 MOFs (opens in new tab)

Polymeric membranes are widely used these days for wastewater treatment applications; however, in pressure-driven filtration processes, their intrinsic hydrophobicity often leads to severe fouling and reduced separation efficiency. In this study, a novel chitosan (CTS)-grafted metal-organic framework (UiO-66-CTS MOF) was synthesized and used as a stable filler in a polysulfone (PSF) matrix to enhance the hydrophilicity of resulting mixed matrix membranes (MMMs) and prevent nanoparticle agglom...
