In this study, three types of ferrites nanoparticles including CoFe 2 O 4 , NiFe 2 O 4 , and ZnFe 2 O 4  were synthesized by microwave-assisted hydrothermal method. The X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR), and field emission scanning electron microscopy (FESEM) were employed to analyze synthesized nanoparticles and fabricated membranes. The morphology of membrane surface was investigated by surface images. The ability of ferrite nanoparticles was evaluated to the separation of sodium salt and heavy metals such as Cr 2+ , Pb 2+ , and Cu 2+  from aqueous solutions. The modified membrane showed the enhancement of membrane surface hydrophilicity, porosity, and mean pore size. The results revealed a significant increase in pure water flux: 152.27, 178, and 172.68 L·m −2 ·h −1  for PES/0.001 wt% of CoFe 2 O 4 , PES/0.001 wt% NiFe 2 O 4 , and PES/0.001 wt% ZnFe 2 O 4  NPs, respectively. Moreover, Na 2 SO 4  rejection was reached 78% at 0.1 wt% of CoFe 2 O 4  NPs. The highest Cr (II) rejection obtained 72% for PES/0.001 wt% of NiFe 2 O 4  NPs while it was 46% for the neat PES membrane. The Pb(II) rejection reached above 75% at 0.1 wt% of CoFe 2 O 4  NPs. The Cu(II) rejection was obtained 75% at 0.1 wt% of CoFe 2 O 4  NPs. The ferrite NPs revealed the high potential of heavy metal removal in the filtration membranes.
