A facile and rapid removal of cationic dyes using hierarchically porous reduced graphene oxide decorated with manganese ferrite

Herein, MnFe2O4/reduced graphene oxide nanoparticles (MrGO) were synthesized for the effective removal of various cationic dyes. The synthesized nanocomposites exhibited high adsorption capacity for removing cationic dyes as malachite green dye MG and methylene blue dye MB reaching 156, and 105 mg/g at 30 °C, respectively. The high surface area of the prepared adsorbent, 95 m2/g, electrostatic interaction, and π-π interaction facilitated dyes...
