PREPARATION OF Fe-AI LAYERED DOUBLE HYDROXIDE AND ITS APPLICATION IN Sb REMOVAL

PREPARATION OF Fe-AI LAYERED DOUBLE HYDROXIDE AND ITS APPLICATION IN Sb REMOVAL

Fe-AI layered double hydroxide (Fe-Al LDH) was prepared from a mixed solution of FeCl sub(2) and AlCl sub(3) at a constant pH by co-precipitation. Simultaneously, amorphous FeO(OH) and Al(OH) sub(3) precipitated. A lower solution pH for the preparation resulted in more Fe-Al LDH in the precipitate,...

Zusammenfassung:Fe-AI layered double hydroxide (Fe-Al LDH) was prepared from a mixed solution of FeCl sub(2) and AlCl sub(3) at a constant pH by co-precipitation. Simultaneously, amorphous FeO(OH) and Al(OH) sub(3) precipitated. A lower solution pH for the preparation resulted in more Fe-Al 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 SbO super(-) sub(3) on the surface of the FeO(OH) contained in the precipitate.
