In this work, the schwertmannite modified by different divalent cations were successfully prepared and used for the adsorption of Cr(VI) and Cu(II) from aqueous solutions. The characterization was measured by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier Transform infrared spectroscopy (FTIR). FTIR results show that the doping of Mg 2+ and Mn 2+ significantly increased the content of hydroxyl group. Moreover, the adsorption kinetic study illustrated that chemisorption mainly controlled the Cr(VI) and Cu(II) removal process. Therefore, schwertmannite modified by doping with divalent cations could be a potential adsorbent for the remediation of Cr(VI) and Cu(II) containing wastewater.
