Intercalation behaviour of benzenecarboxylic acids in the interlayer of hydrotalcite was investigated by using the chemical reaction of rock-salt type magnesium aluminum oxide, Mg0.61Al0.26O, and various benzenecarboxylates in aqueous solutions at 50-70°C. Magnesium aluminum oxide hydrated and combined with benzenecarboxylate ions and hydroxyl ion competitively to form hydrotalcite-like compounds. The amount of benzenecarboxylate ions incorporated in the interlayer of hydrotalcite and the selectivity of anion uptake increased with increasing charge density of the ions.
