Strong association and micellization equilibria of long-chain surfactants

STRONG ASSOCIATION AND MICELLIZATION EQUILIBRIA OF LONG-CHAIN SURFACTANTS [Pg.26]

This model considers micellization as a phase separation process which begins at CMC (saturation concentration of surfactant species in non-micellar form) with micelles as the new phase formed. [Pg.27]

When micelles are present as a new phase, am = 1 + = -tration of micelles at CMC is quite small. Then [Pg.27]

From Gibbs-Helmholtz equation, enthalpy change of micellization is [Pg.27]

In the treatment by the mass action model, micellization is considered as an association-dissociation equilibrium of individual molecules or ions with micelles in the concentration range above CMC. [Pg.27]
