Abstract	Multifunctional magnetic adsorbents containing MnO2 and polyaniline (PANI) with optimized adsorption properties toward heavy metal ions have been developed. In particular, Fe3O4 spheres were chosen as the magnetic core, followed by PANI and MnO2 coating, realizing the formation of Fe3O4/PANI/MnO2 core–shell hybrids. The as-synthesized Fe3O4/PANI/MnO2 core–shell hybrids showed a hierarchical structure with a large surface area and high magnetic saturation value. In comparison with Fe3O4/PANI and Fe3O4/MnO2 core–shell hybrids, Fe3O4/PANI/MnO2 core–shell hybrids displayed the highest adsorption capacity toward heavy metal ions (including Cd(II), Zn(II), Pb(II) and Cu(II)), thanks to the integrated physical and chemical adsorption behaviors resulting from MnO2 inorganic oxide and the PANI polymer. The developed multifunctional Fe3O4/PANI/MnO2 adsorbents synthesized by a facile and economic route are believed to show high potential in environmental remediation for heavy metal removal.
