On mutual interactions in polycomponent surfactant systems

Abstract

In order to confirm the models of mutual interactions in three- or four-component surfactant systems the experimental determinations of the electrophoretic mobility u ₊₀₋ (cm² s⁻¹ V⁻¹) as a function of the molal ratios n/y, k/h, and x/y were carried out. The polycomponent models are (nRhod⁺ + yCl2−SO ⁻₄ )⁰⁻ + (xBlue⁺ + yCl2−SO ⁻₄ )⁺⁰⁻ and (kCl2−NH ⁺₃ + hFluo⁻)⁰ + (xBlue⁺ + yCl2−SO ⁻₄ )⁰ where n, y, x, k, and h correspond to molal fractions. The five chemically different surfactants were used to obtain polycomponent surfactant colloids. The behavior of all examined systems suggests nonuniform mutual interactions.
