FEATURES OF THE EXTRACTION-PHOTOMETRIC DETERMINATION OF ANIONIC SURFACTANTS

Anionic surfactants with acridine yellow and methylene blue are determined by extraction-photometric method. The comparison of these methods is carried out. The determination with acridine yellow is established to be much simpler. Using acridine yellow allows to extend the range of concentrations and significantly reduce the cost of reagents. These methods may be recommended for the determination of anionic surfactants, depending on the conditions of the analysis.
