    Synthesis of porous magnetic ferrite nanowires containing Mn and their application in water treatment
    Hao-Jie Cui , Jian-Wen Shi , Baoling Yuan and Ming-Lai Fu*
    Two kinds of porous magnetic ferrite nanowires containing manganese (MnFe2O4and Mn doped Fe3O4) have been successfully synthesized by thermal decomposition of organometallic compounds, using nitrilotriacetic acid (NA) as a chelating agent to coordinate with various ratios of Fe(II) and Mn(II) ions. The resultant MnFe2O4and Mn doped Fe3O4nanostructures are superparamagnetic, and have magnetization saturation values of about 45.9 and 48.7 emu g−1for MnFe2O4and Mn doped Fe3O4, respectively. The Brunauer–Emmett–Teller specific surface areas of the MnFe2O4and Mn doped Fe3O4are 37.8 and 45.4 m2g−1, respectively. The as-prepared porous MnFe2O4and Mn doped Fe3O4nanowires exhibit excellent ability to remove heavy metal ions and organic pollutant in waste water. In addition, these porous magnetic ferrites may be useful in other fields such as biomedicine and Li-ion batteries.
