This study systematically compares Polyvinylidene fluoride (PVDF) and Polysulfone (PSf) mixed-matrix membranes (MMMs) modified with graphene oxide (GO) for diethanolamine (DEA) removal. PVDF PSf exhibit distinct interactions GO due to their inherent hydrophobic hydrophilic properties, respectively, influencing membrane performance. Membranes were fabricated using the phase inversion method characterized by Scanning Electron Microscopy (SEM), Fourier-Transform Infrared Spectroscopy (FTIR), Contact Angle (CA) analysis. Performance testing revealed superior water permeability DEA rejection PSf/GO membranes. The PSf/GO-0.5 achieved 91.04% 47.45 L/m²·h·bar permeability, outperforming PVDF/GO-0.5, which demonstrated 78.53% 28.32 permeability. While improved performance, excessive loading caused pore clogging, reducing effectiveness. highlights potential of efficient amine removal, offering valuable insights wastewater treatment applications.

Polyvinylidene fluoride (PVDF) membranes represent a potential technology for the in-depth treatment of organic dye-containing wastewater. Nevertheless, intractable membrane fouling and limited versatility have significantly constrained its applications. Herein, through nonsolvent-induced phase inversion method, we successfully fabricated PDA@MgO/PVDF PDA@ZnO/PVDF membranes, which are modified by synergistic action MgO or ZnO nanoparticles with polydopamine (PDA), respectively. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), as well analyses pore structure, contact angle, surface free energy, were utilized to characterize hybrid membranes. The results demonstrate that modification PDA@MgO PDA@ZnO can enhance hydrophilicity, pure flux, dye rejection, pollution resistance PVDF enhanced hydrophilicity from increase in energy polar component term. Comparatively, exhibits smaller angle (69°) higher water flux (378.63 L/m2·h·bar), whereas possesses greater mechanical strength better antifouling performance. achieve rejection rate 94.6% disperse deep blue 79, recovery reach approximately 82%. This research offers novel insights into application

Membrane filtration has been widely used in wastewater treatment; contaminants attached to the membrane surface led flux loss and service life reduction. In present study, a photo-electrocatalysis was fabricated with CNTs@TiO2 deposited on commercial polyethersulfone (PES) (PES/CNTs@TiO2). XRD SEM characterization proved that composites were successfully using one-pot hydrothermal method. Additionally, vacuum distribute as-prepared powder PES membrane. CNTs@TiO2, TiO2 particles outer layer of CNTs, which benefits light adsorption photocatalytic reaction. The hydrophilicity, absorption ability, electron transfer rate PES/CNTs@TiO2 enhanced compared pristine membranes. Organic compound removal improved system improvement 32.41% for methyl orange (MO), 26.24% blue (MB), 7.86% sulfamethoxazole (SMZ), 25.19% florfenicol (FF), respectively. Moreover, hydrophilicity could be restored after pure water cleaning, demonstrating excellent reusability. quenching experiment showed ·OH ·O2− main reactive oxygen species. This work provides convenient form technology modified membranes, great potential practical application.
