The reduction in intensity and the increase in the width of peak at 24.1 Å indicate that the crystallinity of the bentonite is considerably affected by acid activation and the bentonite crystalline structure is decomposing, which means that the activation process is accompanied by the appearance of an amorphous phase, as shown in Figure 2.
Bentonite clay is one of the most widely used clays, due to its physical-chemical properties and its ability to increase the space between its layers after being subjected to an activation process (acidic, alkaline, thermal or mixed) [9]. Acid activation is a chemical treatment that is generally carried out with hydrochloric or sulfuric acid.
