The saturation magnetization of all initial samples was ~1 A*m2/kg, while the saturation magnetization of the samples after phase transformations increases greatly (up to 70 A*m2/kg for synthetic goethite sample). It was shown by X-Ray diffraction method that all phases transformed into magnetite. Rather high saturation magnetization of obtained magnetic particles makes them promising for different medical-biological applications (cells separation, DNA purification, targeted drug delivery, adsorbents of radioactive waste, etc.). popup.nrat_date 2025-05-12 Close
