Magnetite nanoparticles (MNPs) - based nanocomposites
are promising for drinking water and ballast water
treatments due to their easy synthesis and magnetic
recyclability. The bifunctional nanocomposite we recently
prepared by incorporating both MNPs and silver nanoparticles
into activated carbon matrix has demonstrated recoverability
and reusability with high antimicrobial efficiency for water
disinfection. However, prolonged exposure of MNPs to the
dissolved oxygen in water converts iron (II) ions to iron (III)
ions, weakening the magnetic responsiveness and reducing
the recovery rates for the nanocomposites. In this work, we
explore various strategies inhibiting the access of oxygen to
the MNPs and preventing them from being oxidized in water.
This includes capping the MNPs with inorganic, organic, and
surfactant agents. The effectiveness is evaluated based on
their oxidation resistance in water. The nanocomposites with
protected MNPs are evaluated for their recoverability and
ability to remove water pollutants and/or disinfect water.
