Characterization of the Efficiency of Photo-Catalytic Ultrafiltation PES Membrane Modified with Tungsten Oxide in the Removal of Tinzaparin Sodium

One of the polymeric membranes' main limitations is their susceptibility to fouling, lowering membrane's performance with time. Therefore, incorporating nanomaterials in polymer matrices has attracted great attention wastewater treatment applications. It's a promising approach for enhancing membrane hydrophilicity and performance. Herein, ultrafiltration nanocomposite membranes were synthesized by applying phase inversion method through immobilizing (0.1-0.4 wt.%) tungsten oxide (WO2.89) nanoparticles polyether sulfone (PES) matrix. Membrane's anti-fouling was evaluated against tinzaparin sodium. The data showed that pure water flux improved increasing nanoparticle loading, reaching its optimum value 54.9 kg/m2 h at 0.4 wt.% WO2.89 compared neat 30.42 h. results also demonstrated rejection efficiency recovery ratio (FRR) sodium enhanced, 44.89% 12.69%, respectively, modified 0.4wt.% loading PES membrane. after exposing UV light irradiation (λ=365 nm) intensity (1200mW/cm2) 1h, further enhancement 8.34% FRR as same percentage without irradiation. It concluded photocatalytic activity decomposition organic molecules on/close surface impact caused this improvement property
