Magnetic Nanocomposites Fe3O4/FeOOH as a Promising Basis for Advanced Oxidation Processes (Fenton Reaction)
Magnetic nanocomposite particles of Fe3O4/α-FeOOH were synthesized by alkaline coprecipitation from aqueous solutions of di- and trivalent iron salts. The phase composition and magnetic characteristics of the nanocomposite particles as compared to nanoparticles of single-phase Fe3O4 were studied using x-ray structural analysis, Mössbauer spectroscopy, and vibration magnetometry. The sizes of the obtained particles (average diameters of 4-21 nm) and the Debye temperatures ΘD = 273 ± 19 and 327 ± 45 K for Fe3O4 and Fe3O4/FeOOH, respectively, were determined by various methods. The obtained magnetic characteristics of Fe3O4/FeOOH (Ms ≈ 32 emu/g at T = 300 K) allowed this composite material to be used as a reagent in improved oxidation processes followed by magnetic decantation.
