On the Conditions of Change in the Type of the Dependence Curve of the Rehbinder Effect Value on Adsorbate Concentration with an S-Type Isotherm

Abstract

The value of the thermodynamic determination of the Rehbinder effect is studied analytically as a function of adsorbate volume concentration in a liquid solution flowing about a solid surface in the case in which its isotherm has an S-type shape on the undeformed surface. Using a previously developed theory of equilibrium adsorption on a solid surface, taking its deformation and the presence of an electrical charge on it into account, the conditions are derived for the change in type of dependence of the Rehbinder effect value on the adsorbate volume concentration, from domelike to monotonically increasing.
