Abstract

Layered materials of zinc hydroxychloride (ZHC), zinc hydroxynitrate (ZHN) and zinc hydroxysulfate (ZHS) were prepared by the precipitation method. The products were highly crystalline. The pH buffering capacities of the products are high in the pH range from 3 to 10. The zinc hydroxyl salts have a high capacity for adsorbing chromate ions.
