Résumé :

Conductivities of well characterized monodisperse polystyrene latices have been measured. Experimental values of the surface conductance have been obtained from the Street treatment. Surface conductances have been calculated from the Bikerman equation introducing experimental values of the electrokinetic potentials. These are compared with the experimental results. As the Bikerman equation was derived for large Ka, however, an extension of this relation for any Ka value is proposed. The effects of C potential, particle charge and ionic strength on surface conductance have been investigated. © 1972.
