Abstract

Three clay minerals: bentonite, illite and kaolin were treated with acid at different concentration and time. The changes of surface areas, water vapor adsorption energies, variable charge and apparent surface dissociation constants were observed depending on the kind of the mineral and acidification conditions. After acid treatment, the surface area increased for kaolin and illite, but decreased for smectite and the opposite tendency occured for the adsorption energy. For all minerals the amount of variable charge increased and the apparent surface dissociation constant decreased indicating the decrease of the surface acidity strength.
