In this paper, it was tried to synthesize iron oxide nanoparticles in a very small size by using internal raw materials for better efficiency.behaveir nanoparticles in the Membrane.ane matrix determined by various characterizations such as PSA, SEM XRD, and TEM. The results showed that the nanoparticles synthesized in the nitrogen atmosphere have a much smaller size and higher super magnetic properties. The maximum amount of nanoparticles used without their surface modification related to the electromagnetic property of nanoparticles. Distribution and acceptable chemical interactions in the matrix were ۰.۰۳% wt. The maximum separation at ۰.۰۱% wt and flux decreased with an increasing amount of nanoparticles to۰.۰۳% wt, which the results are fully consistent with these results and is based on the type of bonds and their amount and stretching and vibration interaction modes. The optimum amount of nanoparticles in the polyethersulfone matrix ۰.۰۱% wt
