About this site

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.

About this site

A process for making acid-activated bleaching earth from certain naturally occurring mixtures of calcium bentonite and attapulgite clay. The process involves treating such clay with low levels of activating acid which are mixed with the dried and ground clay, or spray dried from slurries containing the clay-acid mixture. Advantages include: lower acid costs/unit mass of clay treated, lower ...

Physico-chemical variation in bentonite by sulfuric acid ...

[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
