Description
Summary:Tables are presented of the repulsive energy due to the interaction of diffuse double layers. The cases of two parallel flat plates and of two spheres are considered both at constant equal surface potential and at constant equal surface charge. The radii of the spheres are assumed to be large compared with the thickness of the double layer ( κa ⪢ 1). Limiting equations are presented for four different cases: small separations, large separations, moderate potentials, and moderate charge densities. The ratios of the flocculation concentrations for mono-, di-, and trivalent ions are computed also, both for constant potential and for constant charge.
