摘要：

The metal-adsorption sites of natural (untreated) kaolinite, montmorillonite, and synthetic mordenite were elucidated by comparing the pH values of their adsorption edges with those of Si and Al oxides. Cation adsorption by these clays is strongly influenced by the Si/Al surface-site ratio, steric effects of interlayers or channels, Lewis acid strength of the metal, and pH of the medium. -from Authors
