Natural Materials Rich in Montmorillonite: Simultaneous Measurement of Expansion and Sorption
AbstraktA combined flow technique for study of sorption properties of clay materials has been developed. First, water desorption is recorded and, subsequently, simultaneous measurements of water adsorption and of clay-bed expansion are performed. The technique is expected to become a powerful tool for determination of the generic type of clay materials and to provide information on the content of smectic components in the clay. From adsorption-desorption runs, data on equilibrium sorption of water in clay and on the sorption kinetics can be obtained.
