- Аннотация: The effect of the nature of a nonpolar phase on the surface activity J of ionic surfactants, the standard free energy of adsorption DELTAG0, and the increment of the standard chemical potential DELTAmu(m)0 required for the methylene group to be transferred from water to a nonpolar interface was studied using systematic precision measurements of the surface tensions sigma for highly diluted aqueous solutions of sodium dodecyl (SDS) and tetradecyl sulfates (STDS) at the air, perfluorodecalin (PFD), and octane interfaces under adsorption equilibrium at 293 K. For expanded adsorbed layers of SDS and STDS at the interface with PFD, in contrast to the water-octane interface, a marked effect of the nonideal mixing of hydrocarbon radicals of adsorbed diphilic ions with PFD molecules was observed.
