Purposes of the research: The finding of the most significant equilibrium and spectral characteristics of associates which consist from cations of cyanines or rhodamines and anions of sulphonephtaleins and oxyxanthenes. The creation of the method of determination of anionic surfactants in aqueous solutions. Methods: Spectrophotometry, luminescence. Theoretical results: Conditions of the associates creation have been investigated in aqueous solutions. The stechiometric schemes of their interactions and influence surfactants on associates have been studied. Practical results: A new method was elaborated for quantitative determination of anionic surfactants with the limit of detection about 1·10-6 mol/dm3.
