Electrostatic and solvation-thermodynamic approaches as a tool to study formation of electrical double layer of ionogenic surfactants micelles

Nikolay Bondarev

Abstract


The solvation-thermodynamic approach to study formation of electrical double layer of ionogenic surfactants micelles is proposed. The equations to estimate the Galvany potential of micelles formed by ionogenic surfactants are proposed. The apparent dissociation constant thermodynamic interpretation of the electrolyte in micellar solutions is given.


Keywords
