Adsorption capacity of bentonite

Adsorption is a natural phenomenon in the presence of all solid substances. The phenomenon of certain molecules gathering on the surface of bentonite is called the adsorption of bentonite.

Bentonite is a kind of clay rock, also called montmorillonite clay rock

Bentonite is a kind of clay rock, also called montmorillonite clay rock, which often contains a small amount of illite, kaolinite, halloysite, chlorite, zeolite, quartz, feldspar, calcite, etc; Generally white, light yellow, and light gray, light green, pink, brownish red, brick red, gray black, etc. due to changes in iron content

Activated clay

Activated clay is an adsorbent made from clay (mainly bentonite) as raw material, which is subjected to inorganic acidification treatment, followed by water rinsing and drying. Its appearance is milky white powder, odorless, tasteless, and has strong adsorption performance. It can adsorb colored and organic substances.

Bentonite is a non-metallic mineral with montmorillonite as the main mineral component

The chemical composition of montmorillonite is (Al2, Mg3) Si4O10OH2 · nH2O. Because of its special properties, such as swelling, cohesiveness, adsorption, catalysis, thixotropy, suspension and cation exchange, it is widely used in various industrial fields.
