This transformation can be considered as an analogue process to that expected in the bentonite barrier from a deep geological repository of radioactive wastes whether the two following conditions would occur: i) an increase of temperature due to the radioactive decay of the fission products, and ii) a supply of Fe as result of the canister corrosion under intermediate redox conditions.
The effect of acid activation on the textural properties of a bentonite from Serbia was investigated using response surface methodology.
The sorption desorption of the cationic pesticide 1,1′-dimethyl-4,4′-bipyridinium 1,1′-dimethyl-4,4′-bipyridinium 1,1′-dimethyl-4,4′-bipyridinium 1,1′-dimethyl-4,4′-bipyridiniumnedichlorideC (M400) and 600 °C (M600) from aqueous solution at 25 °C has been studied using batch exparaquats.
Aquatic macrophyte species numbers and maximum colonisation depths increased following La-bentonite application from a median of 5.5 species to 7.0 species and a median of 1.8 m to 2.5 m, respectively.
The objective of this paper is to present a new occurrence of bentonite from the eastern Amazon in northern Brazil, here referred to as Balsas bentonite.
When DEP was added before the virgin bentonite was dispersed into water, after 16 h, the average size of clays changed slightly, and it is just a litter larger than that of virgin bentonite, from 16.25 to 25.00 μm, which indicates that DEM-8 can inhibit the bentonite swelling effectively.
The purpose of the work is to study the adsorption of gallium III) on bentonite from aqueous solutions.
An earlier study on Indian bentonites by one of the authors suggested that bentonite from Barmer district of Rajasthan (termed Barmer 1 bentonite), India is suited for use as buffer material in deep geological repositories.
The catalytic tests with the modified solids show, in all cases, 100% of phenol conversion after 2 h and total organic carbon (TOC) elimination between 49 and 53%, in 4 h of reaction, results which can be compared with pillared bentonite from diluted suspensions.
The increase in CR adsorption with 20 g L−1 of raw bentonite from 58%% to nearly 100%% was attributed to the increase in surface area of micropores and the increase in availability of vacant adsorption sites (Toor and Jin 2012).
