Abstract: Separation processes with membrane technology have been used extensively for wastewater treatment. In this research, dopamine was applied to synthesize FeDA nanoparticles. Then synthesized iron nanoparticles (FeDA) were used to preparation of nanofiltration membranes by incorporation of different concentrations of nanoparticle as an additive into the PES as membrane matrix. Prepared membranes and synthesized nanoparticles were analyzed by Fourier transform infrared (FT-IR), Scanning electron microscopy (SEM) and X-Ray diffraction analysis (XRD) analysis. The FTIR analysis revealed the formation of desirable bonds in the synthesized nanoparticles. The separation performance of all fabricated membranes was evaluated by pure water flux, flux recovery ratio and Na2SO4 rejection. The results showed that M3 has the highest pure water flux among modified membranes. However, the pure water flux decreased compared with neat PES membrane, but the Na2SO4 rejection increased to 67.4% in 1wt.% of FeDA nanoparticles. Moreover, the fouling resistance of modified membranes enhanced by incorporation these nanoparticles.
