4.9 Mechanism of removal of methylene blue dye after adsorption
on magnetic nanocomposite
Mechanism of removal of methylene blue dye from aqueous solution using a
metal-organic framework nanocomposite containing magnetic nanoparticles
after adsorption onto the nanocomposite surface, in the presence of
hydrogen peroxide as a strong oxidant, this is due to the presence of
iron (II) and hydrogen peroxide in the radical hydroxide medium. The
hydroxide radical rapidly and selectively attacks the organic structure
of the dye and converts the organic compound into the water, carbon
dioxide and inorganic ions. During this reaction, ferrous (II) ions are
converted to ferric (III) and oxide ions.
