| Résumé : | A study was made on the influence of molar volumes and of polarization of tetraisoamylammonium picrate in benzene on the repulsive energy between spherical colloidal particles. The spherical colloidal particles (radius 1 μ) are taken to be at a negative constant surface potential. In comparison with the classical Derjaguin-Landau and Verwey-Overbeek theories, we observe a large increase of the repulsive energy due to the strong polarizability of the tetraisoamylammonium cation, whereas the finite molar volume of this cation weakly decreases the repulsion. All the effects (polarizability, molar volume) increase with the surface potential and the concentration of the solute. © 1971. |
