The influence of charge, hydrophobicity, and spatial characteristics on the analytical signal of cationic and anionic surfactants in their association with fluorescent reagents in aqueous solutions is studied. The increase in the analytical signal of the surfactant and the shift in the position of the fluorescence wavelengths maximum with increasing contribution of the role of electrostatic interactions between the reagent particle and the ionic surfactant have been shown. The presence of extrema under conditions of hydrophobic matching in the study of the effect of hydrophobicity of the reagent and ionic surfactants on the surfactant analytical signal has been shown. The manifestation of the spatial matching between the interacting particles in the study of the influence of the spatial characteristics of the reagents and surfactants has also been shown. The influence of colloidal aggregation of associates formed in the reagent-surfactant system on the value of measurement of the analytical signal of the ionic surfactants in the methods of fluorescence and spectrophotometry has been investigated. The obtained effects made it possible to design an analytical system for the determination of sodium dodecyl sulfate with a fluorescent reagent.
