Effect of the Dielectric Constant on the Double Layer on Clays
Published online by Cambridge University Press: 02 April 2024
Abstract
Electric potentials as a function of distance were calculated for a model of the double layer on clays in which a surface zone a few water molecules thick has a low dielectric constant. This zone is followed by bulk water with a normal dielectric constant. The double layer potentials were found to be lower than those obtained from the Gouy model, in which water has a normal dielectric constant throughout the double layer.
