Abstract

The regularities of the influence of the colloid-chemical state on the analytical signal of cationic surfactants in solutions of associates with the counterion have been investigated. These studies have carried out to create rational conditions for the determination of organic cations using analytical systems with reduced influence of colloidal aggregation of analytical forms. The significant influence of turbidity of solutions on the magnitude of the fluorescence and spectrophotometry analytical signal of cationic surfactants in the association reaction with eosin Y and the accuracy of its measurement has been shown. Herewith, the maximum value of turbidity corresponds to the formation of the reagent–cationic surfactant electroneutral associate and the minimum value of turbidity coincides with the formation of the charged associate. It has been shown that the minimal turbidity of aqueous solutions of reagent–cationic surfactant associates of different hydrophobicity corresponds to the formation of associates of the smallest size. The influence of the colloid-chemical state on the analytical signal of cationic surfactants in solutions of associates with the reagent in the presence of Triton X-100 has been investigated to eliminate the negative effects of colloidal aggregation. The non-ionic surfactant concentration dependences made it possible to trace the largest changes of the scattering factor when adding Triton X-100 to the solution in the field of stoichiometric molar ratios of the associate’s components. It has been found that non-ionic surfactants of the Triton X-100 type eliminate the influence of turbidity and scattering factor on the analytical signal of cationic surfactants.
