Fe-AI layered double hydroxide (Fe-AI LDH) was prepared from a mixed solution of FeCl2 and A1C13 at a constant pH by co-precipitation. Simultaneously, amorphous FeO(OH) and Al(OH)3 precipitated. A lower solution pH for the preparation resulted in more Fe-AI LDH in the precipitate, and the precipitate was able to effectively remove antimonate [Sb(V)] from an aqueous solution. This was attributable to the anion exchange properties of Fe-AI LDH contained in the precipitate, and the adsorption of SbO3- on the surface of the FeO(OH) contained in the precipitate.
