Jute-integrated copper nanoparticle-embedded PSf membrane as highly efficient dye removal material

Abstract

Abstract Membranes are actively used in a broad range of industries, including the water, energy, and biological sectors. Through pore functionalization of membranes of the ultrafiltration (UF), microfiltration (MF), and nanofiltration (NF) types with responsive behaviour, membranes that supply flux, metal sorption, dye sorption, and catalysis have been created. Through the manufacturing of polymers and surface modification, this technology offers a chance to enhance the performance of synthetic membranes. Discharge of hazardous containments, especially dyes and heavy metal ions, to freshwater streams has become a global concern due to many industries overlooking the environmental protocols in wastewater management. In the present study, polysulfone (PSf) membrane composites with high porosity and large internal pore volume were produced on a lab scale by adjusting the polymer coagulation conditions during phase inversion manufacturing and embedding copper nanoparticles for anti-fouling activity and pre-treated natural jute fibers, and the composites' adsorption capacities were measured. The composites were characterized thoroughly via FTIR, SEM, XRD, DLS. Finally, PSf-based membrane composites performances were investigated in terms of rejection (%) using methylene blue (MB) in water solution to assess their potential application in separation and purification processes.
