<p><b>Bentonites</b> are rocks mostly consisting of swelling clay minerals. They were first described from the Cretaceous Benton Shale near Rock River, Wyoming, USA. </p> <p> Because of their useful properties (e.g. highly adsorbent, cation exchanging, swelling), bentonites have many uses, in industry (among them as ...

Calcium bentonite vs sodium bentonite: The potential of calcium bentonite for soil foundation
Materials Today: Proceedings, 2022Abstract Bentonite is a favourable candidate as a sealing material in the deep geological repository to safe storage of highly radioactive nuclear waste in several countries. The high swelling characteristic made bentonite famously type of clay that extracted from smectite group with the main mineral is montmorillonite that has a double diffusion ...

Adsorption of phenol by bentonite
Environmental Pollution, 2000The potential of bentonite for phenol adsorption from aqueous solutions was studied. Batch kinetics and isotherm studies were carried out to evaluate the effect of contact time, initial concentration, pH, presence of solvent, and the desorption characteristics of bentonite. The adsorption of phenol increases with increasing initial phenol concentration

Adsorption of liquid mixtures on bentonite and organophilic bentonite
Journal of Colloid and Interface Science, 1975Selective sorption of binary mixtures has been studied on bentonite and organophilic bentonite. Adsorption excess isotherms on these adsorbents have been determined for benzenen-n-heptane and alcohol-benzene mixtures, and the adsorption capacity of the components has been calculated by the analysis of the excess isotherms. The organocomplex swells only

Compressibility behaviour of bentonite and organically modified bentonite slurry
Géotechnique, 2013Bentonite in slurry walls needs to be amended with organo-clay to control the migration of organic contaminants. Consolidation behaviour of the slurry is important because it will reduce the total effective stress owing to mobilisation of frictional force between the side wall of the trench and the slurry. Compressibility of the slurry of bentonite is

Some Studies of the Autotransformation of H‐Bentonite to Al‐Bentonite
Soil Science Society of America Journal, 1962Abstract Duplicate samples of suspensions of H‐bentonite prepared by the method of Aldrich and Buchanan (1) were heated at 35°, 50°, 65°, 80° and 95°C. At appropriate time intervals, samples were removed, cooled to 25°C., and titrated electrometrically with NaOH solution.
