Studies have been made of the surface characteristics of the schistose silicate, saponite, and samples obtained by acid modification of the mineral. The structural characteristics of the samples were determined via the complete adsorption/desorption isotherms of benzene. It was shown that acid modification of saponite generates materials with improved adsorption–structural characteristics and high adsorption capacity towards small non-polar molecules. By mans of the ionogenic adsorption of dye molecules, electro-osmotic data and DTA, it has been shown that saponite could be used for the creation of effective ion-exchange materials.
