synthesis and characterization of green magnetic iron oxide nanoparticles for ra removal

Iron oxide magnetic nanoparticles (fe3o4-nps) were synthesized using a simple, fast, and environmentally green method. extracts of thyme and rosemary were used in the green synthesis of fe3o4-nps. fourier transform infrared (ft-ir) technology, scanning electron microscopy (sem), energy-dispersive x-ray (edx) spectroscopy, x-ray diffraction (xrd), and mössbauer spectroscopy (ms) have been used for characterization of the prepared material. sem images displayed that the synthesized fe3o4-nps were mostly in spherical shape with sizes ranging between (11 and 17 nm) and between (8 and 16 nm) when using thyme extract (0.5%) and rosemary extract (0.5%), respectively. the xrd results revealed that the prepared materials showed high purity and crystallinity of fe3o4-nps. the synthesized fe3o4-nps were also confirmed using ft-ir analysis. mössbauer’s analysis showed quadrupole splitting in compounds. properties. the synthesized fe3o4-nps were applied as absorbent materials to remove the 226ra from the coproduced water with oil production successfully.
