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.
