Facile synthesis of hyperbranched magnetic nanospheres for highly efficient removal of methyl orange

Abstract

Amino-terminated hyperbranched polymer (ATHP1) coated magnetic microspheres (Fe3O4–ATHP1) was synthesized using amino-modified ferric tetroxide (Fe3O4–NH2) as the core and glutaraldehyde as a cross-linking agent. The adsorption properties of Fe3O4–ATHP1 and Fe3O4–NH2 for methyl orange (MO) adsorption were investigated and compared. ATHP1 functionalization was found to significantly improve the MO adsorption properties of the magnetic material. It was proved that Fe3O4–ATHP1 exhibited excellent adsorption performance at pH values ranging from 3 to 10 and in concentrations ranging from 10 mg L−1 to 50 mg L−1. Besides, easy separation and good recyclability were also observed for Fe3O4–ATHP1; after six cycles, it still had an over 78% removal capacity for methyl orange. The adsorption mechanism was also studied, and the MO adsorption mechanism on Fe3O4–ATHP1 followed the pseudo-secondary kinetic model and the Langmuir adsorption isothermal model.
