activation of bentonite by organic acid


Preparation of activated bentonite and its adsorption

In previous studies, the common method used in preparation of activated bentonite was either water-bath heating or hydrothermal process with acids (Oladipo and Gazi, 2014), which needed a long reaction time and was of low-efficiency.

Acid Activation - an overview | ScienceDirect Topics

Acid-activated bentonites are high-added-value specialty clays and so are organophilic bentonites, which are prepared by replacement of the exchangeable cations by suitable organic cations. Organophilic bentonites are hydrophobic and are used for the preparation of CPN, with enhanced properties ( Bergaya and Lagaly, 2007, Bergaya et al., 2011 ).
