Effect of Magnetic Field on Prepared Magnetic Nanocomposite Membrane Structure and Perfomance

The main goal of this study is to fabrication of magnetic nanocomposite membrane with sufficient sensitivityto external magnetic field. For this purpose iron oxide nanoparticles (about 70 nm) were synthesized through oprecipitation,blended with polysulfone solution and finally dispersed in membrane structure after coagulation of castedpolymeric solution. Effect of magnetic nanoparticle on membrane structure and filtration performance was studied.According to filtration experiments, the increasing of nanoparticle concentration in membrane matrix causes permissionflux to rise. On the other side any increases in magnetic field intensity improves membrane water flux. In fact iron oxidenanoparticles in polymeric solution act as an agent to increase membrane hydrophilicity, and consequently water fluxenhancement. SEM images showed the presence of nanoparticle in the membrane structure. The cross section of whichconfirmed the effect of magnetic field on membrane pore direction.
