The contribution of H 2 O 2 on the generation of functional groups in montmorillonite was analyzed using FTIR spectra (Fig. 1 c and d). The peak at 3630 cm −1 was attributed to the stretching vibrations of Si–O–H and Al–O–H (Abdel-Karim et al., 2021).The peaks at 3437 cm −1 and 1640 cm −1 were resulted from the stretching and …

Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding ...
FTIR spectra reflected the changes in the functional groups of the material before and after ball milling (Fig. 1 b).The peak at 3630 cm −1 was caused by the O–H stretching vibration of Al–OH in Mt. The peaks at 3437 cm −1 and 1640 cm −1 were attributed to the stretching vibration and bending vibration of the water –OH structure in …
The characteristic diffraction peaks of montmorillonite at 19.89°, 26.64°, 35.30°, 62.80° were ascribed to the typical crystal structure of bentonite 44,45.

The OMMT was synthesized through the intercalation modification of sodium montmorillonite (Na-MMT) with cationic cetyltrimethylammonium bromide (CTAB), nonionic nonylphenol polyoxyethylene ether (NPE) and the mixture of them via simple and convenient wet ball-milling method.
Bentonite contents affects ability to absorb water. An example of how a dried piece of clay having lower bentonite content (left) absorbs a drop of water faster. After 10 seconds (middle picture) the water is gone while the other is still wet. By 30 seconds (bottom) all traces of water are gone. National Standard Bentonite fired to 1650F in a ...
In addition, the energy consumed by the ball mill for similar fineness (5 µm) was approximately 300 kWh/t energy, whereas the stirred media mill consumes approximately 174 kWh/t energy.
However, Bentonite clay is primarily composed of montmorillonite, while Montmorillonite clay is almost entirely made up of montmorillonite. This difference in composition gives them distinct properties and applications.

Bentonite and montmorillonite. Bentonite is a natural clay containing clay minerals in the smectite group that was formed by devitrification of volcanic ash that fell into water (Eisenhour and Brown 2009). Bentonite was named after Fort Benton near Rock River, Wyoming, USA where it was originally found, by W.C. Knight in 1898.
Mechanochemical activation can be defined as a process able to induce structural disorder through intensive grinding. In certain conditions, it may increase the chemical reactivity of the processed material. The process is extensively utilized in extractive metallurgy, synthesis of nanocomposites or pharmacology. It is also …
