| Résumé : | A local thermodynamic method was employed to calculate the potential, the field, and the surface charge in the diffuse layer around a colloidal particle. It was found that the effect of the molar volume of the counterions and the effect of the polarization were to lower the local concentration of the counterions and thus to reduce the surface charge for a given surface potential. The ratio of the surface charge calculated by this theory to that calculated by the Gouy-Chapman theory does not change significantly with the curvature of the colloidal particle. A limitation in the application of this theory is due to the lack of knowledge of the activity coefficients at zero field in the diffuse layer. Two nomograms (graphs) of the potential versus charge relation are presented. © 1968. |
