Since the first report on the magadiite and kenyaite minerals found in Kenya (1967), the preparation, characterization and uses of layered alkali silicates have been reported extensively. Ion exchange ability is one of the most important and useful characteristics of the layered alkali silicates, therefore, the ion exchange of layered alkali silicates with various inorganic, organic and organo-metallic cations have been investigated from the mineralogical, structural, chemical and application viewpoints. Among the layered alkali silicates, magadiite occupies the special position due to the ease of preparation and the structural stability and reactivity. In this review article, metal ion adsorption on magadiite was overviewed.
