Long chain ionic surfactants: the understanding of adsorption mechanisms from the resolution of adsorption isotherms

The authors present the different steps required for understanding the adsorption of long chain ionic surfactants at the solid-aqueous solution interface. First, the physical chemistry of the surfactant in solution has to be well documented. This requires to know the phase diagram of the surfactant that yields the Krafft point and the value of the critical micellar concentration (CMC) of the spherical micellar phase (T>T-Krafft) or the saturation concentration of the hydrated-crystal phase (T
