An electrokinetic study of micellar solutions

Abstract

A theory is developed which enables the conductivity of a micellar suspension to be interpreted in terms of a zeta potential and applied to conductivity measurements on SDS in NaCl solutions. This conductivity derived zeta potential is compared with the zeta potential obtained from mobilities measured by D. Stigter and K.J. Mysels, (J. Phys. Chem. 45, 59 (1955)). Good agreement is obtained over a wide electrolyte concentration range using the hydrodynamic radii obtained from neutron scattering for the theoretical interpretation. © 1990.
