Bentonite - Wikipedia

Calcium bentonite may be converted to sodium bentonite (termed sodium beneficiation or sodium activation) to exhibit many of sodium bentonite's properties by an ion exchange process. In common usage, this means adding 5–10% of a soluble sodium salt such as sodium carbonate to wet bentonite, mixing well, and allowing time for the ion exchange ...

Acid Activated Clay Adsorption Properties

Acid Treatment of Bentonite: Under the influence of a mineral acid the exchangeable alkaline earth ions of bentonite are substituted by hydrogen ions. Moreover, depending on the acid concentration, temperature, pressure and reaction time, a more or less pronounced leaching process takes place. Thereby Al-, Fe- and Mg-ions are extracted from the octahedron layers.

Surface Changes in an Original and Activated Bentonite

in the activated bentonite. Apparently, the ad­ sorbed water is retained more weakly in the activated material than in the original bentonite. The slight minimum at 690° C for the activated material indicates the removal of a large part of constitutional hydroxyl groups as a result of the acid activation process.
