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 sulphonenphtaleins and oxyxanthenes. 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 cationic surfactants with the limit of detection about 1·10-6 mol/dm3.
