Characterization of activated bentonite clay mineral and the …

Clay minerals are considered as the most effective adsorbents due to their considerable specific surface area, pore-volume, negative surface charge, and hydrophilic surface (Srinivasan 2011; Uddin 2017). Bentonite is an inorganic 2:1 type clay mineral, which is mainly constituted of montmorillonite (Maged et al. 2020).
