摘要: The potential,ϕ0, of the diffuse electric layer was determined by equilibrium liquid film method (1). is based on calculating theϕ0-potential means DLVO theory electrostatic disjoining pressure at known concentration,Cel solution forming microscopic and thickness,hr film. thickness measured microinterferometric (7, 8). calculation potential carrried out more general eqs. [2] [3], valid for a wide range ofCel andϕ0. dependence concentration surface activ agent (surfactant) stabilizing found. It established that ionogenic SAS show higher than non-ionogenic ones. SAS-free solutions — ca. 30 mV.
