Bimetallic oxides were synthesized from hydrotalcite using increasing calcination temperatures (873, 1073, 1273 K). These bimetallic oxides were fully characterized and the sorption density of F− was investigated. X-ray diffraction patterns for the products showed that MgO was present in the phase within the range of investigated calcination temperatures, but MgO crystallinity increased with calcination temperature and an additional MgAl2O4 phase was formed. In the process of F− sorption, the bimetallic oxides were primarily transformed into hydrotalcite with intercalation of F−. The higher calcination temperature increased the MgAl2O4 phase, which did not contribute to the immobilization of F−. These findings show that optimizing the calcination temperature can be used to maximize the sorption density of this material for F− removal.
