ACs@ZnO incorporated with a PSF/PU polymer membrane for dye removal

Abstract

Membranes were made utilizing a straightforward, non-destructive, and environmentally friendly method for the protection of people's health and the environment. In this study, the phase inversion method is applied to create a low-cost wastewater treatment membrane from raw materials. A common organic contaminant with a negative reputation for affecting aquatic life is dye. The prepared membrane is characterized using a range of instrumental approaches. To develop a membrane, polysulfone (PSF) and polyurethane (PU) were blended with activated carbon and green synthesis of ZnO nanoparticles for water treatment. By using SEM, TEM, FTIR, contact angle, and XRD, the produced membrane, nanoparticles, and additives validated its morphological alterations, structural arrangement, hydrophilicity, and crystalline confirmation. Banana peel was used to create ZnO nanoparticles and activated carbon from coconut shells and its mixed matrix membrane was used for the efficacy test after Congo red and methylene blue were removed. UV spectroscopy exhibits strong absorption capacity and may be crucial in membrane maintenance. As a result, the produced membrane may serve as a substrate for dye removal.
