Bentonite - Wikipedia

Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite.It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.. The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al).

What is Activated Clay? (with picture)

 · Activated clay is clay, usually of bentonite origin, which has been treated to improve its ability to adsorb. The clay is processed with acid, upping the adsorption properties of the clay considerably. Once it has been treated, activated clay can also be reactivated as it is used, allowing people to reuse the clay rather than having to continually replace it.

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.
