Electroviscosity. III. Sedimentation Phenomena in Ionic Liquids
1949
Proceedings of the Royal Society A
It is demonstrated that the rate of sedimentation of a system of particles in an ionic liquid may vary markedly with the ionic concentration, due to variation in the electroviscous forces which resist shear in the double layer of ions associated with each particle. Equations governing the rate of sedimentation are derived, and used to calculate values for the electrokinetic potentials of carborundum in potassium chloride solutions, from data on sedimenta tion velocity. These values are compared
