Acid activation of bentonite clay for recycled automotive
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.
