Acid Activation of Clay Minerals - ScienceDirect

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.
