A novel super-hydrophilic PSf/HAO nanocomposite ultrafiltration membrane for efficient separation of oil/water emulsion
In this work, flat sheet polysulfone (PSf)-based membranes modified with inorganic hydrous aluminum oxide (HAO) nanoparticles were used as antifouling ultrafiltration membranes for removing oil molecules from oily solution. SEM, AFM and FTIR analyses were performed on the fabricated membranes to stu...
