Chapter 7.1 Acid Activation of Clay Minerals - ScienceDirect

Bentonite is usually a Ca 2+-bentonite treated with inorganic acids to replace divalent calcium ions with monovalent hydrogen ions and to leach out ferric, ferrous, aluminum and magnesium ions, thus altering the layers of smectite and increasing the specific surface area and porosity. This results in the production of bleaching earths, clays suitable for a range of bleaching or decolorizing applications in which they compete against natural bleaching earths.
