Innovations in the Use of Bentonite in Oenology
Bentonite is used in oenology to improve the limpidity and the stability of wine and to predict the formation of deposits in the bottle. The exchangeable cations in its lamellar structures strongly influence some properties, such as the specific surface, the exchange capacity and the adsorption behavior.

Geochemical studies reveal that the Lower Cambrian K-bentonite samples are plotted in the fields of trachyte, trachyandesite, rhyodacite (dacite), and rhyolite in a plot of Nb/Y against Zr/TiO 2, suggesting that the K-bentonites are most probably derived from felsic magmas with sub-alkaline to alkaline nature.
Adsorption of cesium on domestic bentonites | SpringerLink
Bentonite is generally considered as the most appropriate clay material [ 2 – 6 ]. Out of the group of Cs radio-isotopes the most significant one is 137 Cs (T ~ 30.1 years, E β = 0.51 (92%), 1.18 (8%) MeV, Eγ ( 137m Ba) = 0.6616 MeV, Fig. 2 ). Fission nuclear reactions, nuclear explosions and nuclear energetic are the main sources of its existence.
