Determining the Boundaries of the Concentration Area of Action of the Rehbinder Effect for an S-shaped Adsorption Isotherm

This paper continues a study of the magnitude of thermodynamic estimation of the Rehbinder effect as a function of volume concentration in a liquid solution of a surface-active substance (surfactant) in the case of an S-shaped adsorption isotherm on an undeformed and uncharged surface. A generally piecewise linear approximation of the isotherm is used. The conditions of existence of a bounded concentration action area of the Rehbinder effect, such that the area does not fall outside the bounds of defining data from the adsorption isotherm, are derived analytically in terms of theory parameters. The width of this area is compared to the data in the literature on the Rehbinder effect for quartz and granite obtained during dodecyltrimethylammonium bromide adsorption.
