Controllable Preparation of Superparamagnetic Fe₃O₄@La(OH)₃ Inorganic Polymer for Rapid Adsorption and Separation of Phosphate.

ABSTRACT: Superparamagnetic Fe₃O₄ particles have been synthesized by solvothermal method, and a layer of dense silica sol polymer is coated on the surface prepared by sol-gel technique; then La(OH)₃ covered the surface of silica sol polymer in an irregular shape by controlled in situ growth technology. These magnetic materials are characterized by TEM, FT-IR, XRD, SEM, EDS and VSM; the results show that La(OH)₃ nanoparticles have successfully modified on Fe₃O₄ surface. The prepared Fe₃O₄@La(OH)₃ inorganic polymer has been used as adsorbent to remove phosphate efficiently. The effects of solution pH, adsorbent dosage and co-existing ions on phosphate removal are investigated. Moreover, the adsorption ki
