Revolutionizing Water Treatment: Enhanced Flux and Selectivity in Polyethersulfone Mixed Matrix Membrane through Magnetic CuO-Functionalized Fe3O4 Nanoparticles for Synthetic Oily Produced Water Remediation
Surfaces and Interfaces(2024)
摘要
In this research, we present a novel CuO@Fe3O4/PES nanocomposite membrane designed to address the complex challenge of separating oil from synthetic oily produced water. This exceptional membrane demonstrates remarkable separation capabilities, achieving an impressive oil rejection rate of 97.5% and an exceptionally high permeate flux of 0.095 L/m2·h, surpassing traditional pure PES membranes. Our dedicated efforts to optimize membrane efficiency involved a thorough exploration of critical parameters. The peak performance was unequivocally achieved with a solution dosage of 60 mL, a solution concentration of 60 mg·L−1, and a pump pressure of 1.5 bar, ensuring comprehensive optimization. Moreover, contact angle measurements revealed significantly improved hydrophilicity of the CuO@Fe3O4/PES membrane compared to the PES blank membrane. Additionally, SEM, XRD, and FTIR analyses provided valuable insights into the composition, morphology, and properties of the membrane. The outstanding performance of the membrane is attributed to the incorporation of CuO@Fe3O4 nanoparticles, which enhance surface area, permeability, mechanical strength, and catalytic emulsion decomposition. This innovative approach holds great promise for applications in treating oily produced water across diverse industries.
