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 ).

Acid Activated Clay

Acid-activated clays are produced almost exclusively from southern or nonswelling bentonites by treatment with various mineral acids. When used for their ability to decolorize or "bleach" color pigments from vegetable and petroleum oils, they are called bleaching clays or bleaching earths. Although sometimes confused with fuller's earths, which are also sometimes called bleaching clays ...
