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.
