Abstract

The mutual diffusion coefficients, Dij, of the ternary system sodium cholate (NaC, component 1)+sodium deoxycholate (NadC, component 2)+water have been determined at five average compositions (c1, c2) keeping c1 constant and varying c2. The possibility to obtain expressions for the four diffusion coefficients in term of the micellization parameters and of the diffusivity of the species in solution is discussed. Data have been qualitatively interpreted. Results for the main term diffusion coefficients have been used in the much more difficult analysis of the cross term diffusion coefficients.
