Developing a novel polysulfone/chitosan membrane incorporated with green synthesized <scp>CuO</scp> from aloe vera extract for toxic dye removal

Abstract The environment and public health have been protected by the simple, non‐destructive, and ecologically benign process used for fabricating membranes. In this study, a low‐cost wastewater treatment membrane is made from raw materials followed by phase inversion approach. A typical organic pollutant that has earned a poor track record for gradually harming aquatic life. Thus, the membrane technology is used to minimize the water contaminated by dyes. To treat wastewater, a membrane was developed by combining green synthesized CuO nanoparticles with polysulfone (PS) and chitosan (CS). The developed membranes were analyzed using x‐ray photoelectron spectroscopy, contact angle, Fourier transform infrared, scanning electron microscopy, transmission electron microscope, and x‐ray diffraction techniques. The developed membrane, along with the nanoparticles and additives, confirmed its crystalline confirmation, hydrophilicity, arrangement of structures, and morphological modifications. CuO nanoparticles were prepared using aloe vera extract, and incorporated into a mixed matrix membrane was utilized for the congo red (CR) and methylene blue (MB) adsorption processes. The absorption capacity was analyzed via UV spectroscopy makes it potentially important for membrane performance. Therefore, the resulting membrane could be used as a substrate for dye removal applications.
