Porous magnesium oxide microspheres were obtained by calcination of the Mg5(CO3)2•4H2O microsphere precursor. Mg5(CO3)2•4H2O was synthesized using magnesium chloride hexahydrate and sodium carbonate. MgO and Mg5(CO3)2•4H2O were characterized by SEM, XRD, EDS, and XPS. The fluoride removal properties of magnesium oxides were investigated, including adsorption kinetics, adsorption isotherms, and influences of coexisting anions and pH. The MgO microspheres showed a higher capacity for fluorine removal. |
