The results obtained from the mineralogical and chemical characterization confirm that this material, in comparison to some reference bentonites from the Clay Mineral Society Source Clays, has promise as an engineering material, indicating its possible use in various research and industrial applications.
The bentonite from Kutch region of Gujrat, India was used for the experimental work and had the following specifications: liquid limit, plastic limit, shrinkage limit, and sand content are equal to 498, 54.36, 12 and 0.53 % respectively.
In this study, the mineralogical and chemical makeup of the bentonite from a geosynthetic clay liner (GCL) was extensively characterized using a combination of conventional benchtop X-ray diffraction (XRD) and micro X-ray diffraction (μXRD) with synchrotron-generated micro X-ray fluorescence (μXRF) elemental mapping and μXRD (S-μXRD).
The purpose of the work is to study the adsorption of gallium III) on bentonite from aqueous solutions.
The effect of acid activation on the textural properties of a bentonite from Serbia was investigated using response surface methodology.
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).
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 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.
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 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.
