Mixed Matrix Polysulfone Membrane Entrapped With Silicon Dioxide And Polyvinylpyrrolidone For Oil Emulsion Removal

Membranes have been known widely to treat emulsified water. New membrane technology has been fabricated to overcome hydrophobic phenomenon that occurred during separation of oil emulsion. In this study, polysulfone (PSf) membranes were fabricated with silicon dioxide (SiO2) nanoparticles to modify t...
