Abstract:
Al–Zn and Al–Ni layered double hydroxides were synthesized via coprecipitation from solutions of aluminum, zinc and nickel salts at fixed ratios and isolated as polycrystalline samples. The adsorption properties of layered double hydroxides are affected by the nature of the anion in the interlayer space and of the cation in the layers of these compounds.
Keywords:layered double hydroxides, adsorption, nickel, zinc, active acid–base sites.
