Acid Activation - an overview ScienceDirect Topics

P. Komadel, J. Madejová, in Developments in Clay Science, 2013 Abstract. Acid activation is a common chemical modification of clays, usually bentonites, with a hot solution of a mineral acid (typically HCl or H 2 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.

[7]. Activation of bentonite by acid is an important step for adsorp-tion of some impurities by active clay. This is so-called “activation process.” The activation of bentonite is carried out in a continuous stirred tank reactor at low temperatures between 70 and 120oC in the presence of activation agents, mostly sulfuric acid. During the
