Fe-Mn binary oxides have superior catalytic and oxidation performance, and calcined layered double hydroxides (LDOs) have stably dispersed metals and a large specific surface area. Combining the advantages of both, MgFeMn-LDOs were prepared by co-precipitation and calcination, and applied to monovalent thallium (Tl(I)) removal in aqueous. MgFeMn-LDOs before and after Tl(I) adsorption were characterized by scanning electron microscopy (SEM) equipped with an energy dispersive spectrometer (EDS), X-ray Diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The adsorbent has abundan...
