Characterization of activated bentonite clay mineral and the …
Acid activation technique was opted for modifying natural bentonite (NB) to enhance the adsorptive removal of CIP from water. The BET surface area analysis revealed that acid-activated bentonite (AAB) possessed more than two fold higher surface area as compared to NB.

Acid activation affects the pH and porosity of the bentonites. The void volumes in the solid particles with internal widths of <2, 2–50 and >50 nm are called micropores, mesopores and macropores, respectively (Rouquerol et al., 2014).

Acid activated clays: Materials in continuous demand
Acid activation is a chemical treatment traditionally used on clays, typically bentonites in hydrochloric or sulphuric acid, to obtain partly dissolved materials with enhanced surface properties suitable for new applications or displaying interesting new behaviour.

Acid Activation
Acid activation is a common chemical modification of clays, usually bentonites, with a hot solution of a mineral acid (typically HCl or H2 SO 4), and it is used for both scientific and industrial purposes. The aim is to obtain partly dissolved material of increased specific surface area, porosity and surface acidity.

The Kütahya calcium bentonite (CaB) from Turkey shows significant changes in crystal structure, chemical composition and porosity with H 2 SO 4 activation realized by heating its acidic aqueous suspension at 97 °C for 6 h. The acid content was changed from zero to 70% by mass, based on the dry bentonite–acid mixture.
