Long-term stable metal organic framework (MOF) based mixed matrix membranes for ultrafiltration

In this study, novel mixed matrix membranes (MMMs) were synthesised by adding metal organic frameworks (MOFs) (UiO-66 and UiO-66-NH 2 ) to pristine sulfonated polyethersulfone (PES). The differing synthetic method resulting in MMM where additives grafted the polymer, or formed a natural interface, allowing impact of these features be investigated. composite characterised FTIR, PXRD, water contact angle, porosity, pore size, etc. Membrane performance was investigated permeation flux, flux recovery ratio, fouling resistance anti-fouling performance. stability test also conducted for all prepared membranes. A higher reduction angle observed after both MOFs PES compared An enhancement membrane embedding into matrix, with increased remarkably (565 LMH PES+UiO-66-NH at 5% loading 487.1 SPES-UiO-66(10% binding) while BSA rejection still kept high level. By ratio greatly (more than 99% most membranes). showed protein adsorption After immersing 3 months, 6 months 12 stable retained their structure. This study indicates that UiO-66 are great candidates designing long-term applications wastewater treatment. • embedded SPES matrix. hydrophilic show super ratio. property. maintained months.
