  • Magnetic core coated inorganic ion adsorbent for removing Cs ions in radioactive wastewater and preparation method thereof
    Patent number: 9586191
    Abstract: The invention discloses a micron-grade magnetic core coated ferrocyanide adsorbent for removing Cs ions in radioactive wastewater and a preparation method thereof. The adsorbent takes magnetic Fe3O4 as a core, the surface is coated with a dense SiO2 single layer serving as a protective layer, and an active component is metal ion stabilized potassium ferrocyanide coated on the outer layer, wherein stabilized metal ions comprise Ti, Zn, Cu, Ni, Co, and Zr. The particle size of the adsorbent is 0.2-5 ?m, the adsorbent in the outermost layer is conductive to improving the adsorption efficiency for Cs+ ions, and an external magnetic field is adopted for realizing solid-liquid phase separation.
