The purpose of the scientific research work is the metrological ground for multicomponent analysis. The work is performed using spectrophotometric method. A simulation on computer is performed as well. The methods of simultaneous determination of anionic surfactants, using two-dimensional spectra (data arrays) of dependencies absorbance on wavelength and pH or the yield of analytical form, are investigated and compared. As analytical forms, which degree of extraction depend on pH of the water phase and on the number of multi-step solvent extraction, ionic associates of surfactants with Methylene Blue and Rhodamine 6G are reviewed. Variants of determination of anionic surfactants of different classes, which can be a part of systematic analysis of their mixtures, have been developed.
