Surface activity coefficients of spread monolayers of behenic acid salts at air–water interface

Volumetric and Surface Properties of Short Chain Alcohols in Aqueous Solution–Air Systems at 293 K

“…1 it can be expected that the activity of each alcohol in the surface monolayer, determined from Eq. 12 on the assumption that the molar area does not depend on the type of alcohol (1.26 × 10 5  m 2 ·mol −1 ) [34] and its concentration, should be the same as that calculated from the following equation [40]:where π is the difference between water and aqueous solution surface tensions, and π max is the difference between the water and alcohol surface tensions.…”

The adsorption properties of short chain alcohols and Triton X-100 mixtures at the water–air interface

“…In the case of solution of ''pure" alcohol it is possible to establish the surface activity coefficient f S 2 À Á basing on the analogous form of the Raoult's law for the surface plane of the monolayer phase, which can be written as [34]:…”

Behavior of cationic surfactants and short-chain alcohols in mixed surface layers at water–air and polymer–water interfaces with regard to polymer wettability

“…On the basis of this concentration for surfactant and alcohol per unit of area it is possible to determine the composition of the surface layer, namely the molar fraction of surfactant 1 (X S 1 ) and alcohol (X S 2 ) forming 1 m 2 surface plane using the equations [47] C ðrÞ 0 NA 0 þ C ðrÞ SL;1 NA 1 þ C ðrÞ SL;2 NA 2 ¼ 1; ð14Þ…”
