Unpublished results in this laboratory have confirmed this fact. The purpose of this investigation was to learn whether the lower efficiency of clays, which are natural alumino-silicates, is due to differences in certain measurable physical properties, such as surface area, pore sizes, porosity, and density, or to differences in the chemical nature of the surface. 64 pp reformatted digital eng Copyright is held by the author, unless otherwise indicated.
