Catalytic synthesis of graphene-like polyaniline derivative - MFe2O4 (M; Cu, Mn) nanohybrid as multifunctionality water decontaminant

Magnetic MnFe2O4 and CuFe2O4 - 2-aminobenzoic acid phenylenediamine nanocomposite was prepared using the catalytic activity of the magnetic ferrites as an efficient oxidizer. Antimicrobial activity of nanocomposite has been studied by capturing of Bacillus subtilis as sample pathogenic contaminant. Moreover, the nanocomposite was applied for selective adsorption of copper ions as well as methylene blue removal from aqueous solution. Dye and metal adsorption equilibrium time were 1 and 5 min and adsorption followed the second-order model. Moreover, the sorbent can be considered as dye super adsorbent with a capacity of 7089 mg of methylene blue per gram of adsorbent.
