in this study, PVP as pore former, N- methylpyrrolidone (NMP) as solvent and deionized water as non-solventwere used for preparation of the Nanocomposite membranes. The effects of iron-nickel oxide (Fe2NiO4) nanoparticles asinorganic modifier on the preparation of underused Poly phenylene ether ether sulfone (PEES) nanofiltration membraneswere investigated. Pure water flux (PWF) carried out in membrane characterization. Moreover, retention performance inseparation MgSO4 (2000 mg/Lit) from aqueous solution were analyzed for fabricating membranes. PWF and rejectionof pristine PEES membrane increased from 9.66 to 14.78 (lit/m2.h) and 80 to 93%, respectively by blending 0.02 wt%Fe2NiO4 nanoparticles and 5 wt% ethanol.
