Role of Counterion in the Adsorption Behavior of 1:1 Ionic Surfactants at Fluid Interfaces-Adsorption Properties of Alkali Perfluoro-n-octanoates at the Air/Water Interface
Equilibrium surface tension (σe) versus bulk concentration (c) isotherms of aqueous, surface-chemically pure solutions of various alkali perfluoro-n-octanoates were measured at 295 K. These 1:1 ionic surfactant systems belong to the pseudo nonionic ones. Evaluating the different σe vs log c isotherm...
