When bentonites are acid-activated by hot mineral acid solutions, hydrogen ions attack the aluminosilicate layers via the interlayer region (Taylor and Jenkins, 1987). This process alters the structure, chemical composition, and physical properties of the clay while increasing its adsorption capacity (Mokaya et al., 1993).
