Abstract

This research concentrates on a synthesis, preparation, and characterization of a novel type of mixed matrix membrane (MMM) comprised of polyethersulfone (PES) impregnated with tungsten trioxide nanowires (WO3NWs) and iron oxide (Fe2O3) nanoparticles. The MMM fabrication process involved controlled incorporation of WO3NWs and Fe2O3 nanoparticles into the PES matrix to enhance the membrane's separation performance. The resulting mixed matrix membranes were characterized using various analytical techniques, including Field Emission Scanning Electron Microscopy (FESEM) and Fourier-transform infrared spectroscopy (FTIR), to assess their structural, morphological, and chemical properties. The permeation and separation capabilities of the developed membranes were evaluated for diverse applications, such as gas separation and water purification. Preliminary results demonstrate the potential of the PES-WO3NW@Fe2O3 MMMs to exhibit improved selectivity and permeability compared to pristine PES membranes. This work contributes to the advancement of mixed matrix membrane technology and provides insights into the synergistic effects of incorporating nanowires and nanoparticles to enhance membrane performance. Then, the prepared pristine and nanocomposite membranes separation performance and antifouling characteristics at 3 bar operating pressure, temperature of 27 and two concentrations of Congo Red dye at 50, and 200 ppm. The experimental findings indicate that the inclusion of WO3 nanowires into the polymer matrix of PES-PEG leads to an enhancement in the penetration flow, Congo Red rejection and flux recovery ratio (FRR) to 260 L/m2.h, 98.83 %, and 99.52%, respectively. at 0.3 wt. % loading of WO3 nanowire as an optimum filler loading.
