FIELD: chemistry.
SUBSTANCE: invention relates to analytical chemistry and relates to a method for fluorescent identification and determination of concentration of components of tank mixture. Method involves taking an aliquot of the analyzed solution, diluting it, measuring the fluorescence intensity and determining the concentration of the fluorescent substance. Note here that fluorescent marker is introduced into each component of tank mix at production stage. Aliquot is diluted with organic polar solvent with dielectric permeability equal to 12–50 F/m in volume ratio of aliquot : organic solvent equal to 1–4:1–5. Content of the component in the tank mixture is determined from the concentration of the fluorescent marker.
EFFECT: technical result is higher accuracy of preparing solutions and enabling determination of counterfeit products.
