The efficient mixed matrix antifouling membrane for surfactant stabilized oil-in-water nanoemulsion separation

Abstract Membrane technology has raised considerable interest in sustainable water purification over the past decade. The development of antifouling membranes is always the basic approach to address the omnipresent bottlenecks of the membrane fouling. In this study, AlSi2O6 nanoparticles were synthesized using a coprecipitation technique and their influence was investigated on the permeation and antifouling properties of ultrafiltration (UF) membranes of polysulfone (PSF). A series of membranes were fabricated with various concentrations (such as 0.0, 2.5, 5 and 7.5 wt%) of AlSi2O6 nanoparticles through diffusion induced phase separation method. The prepared composite membranes demonstrate …
