Abstract
A procedure is developed for the determination of anionic surfactants (ASs) in water-oil emulsions by impedance spectroscopy with the chemometric processing of experimental data. The conditions of recording impedance titration curves were optimized and the performance characteristics of the procedure were estimated. It was shown that impedance spectroscopic titration is applicable to the determination of AS in aqueous solutions and water-oil emulsions in the presence of organic and inorganic substances. Examples of determination of ASs based on sodium olefin sulfonate are given.
