Utilizing the principle of the additivity of fluorescence, the simultaneous determination of isomers of naphthylamine in a mixture of these, zirconium and hafnium with morin, and of samarium and europium with thenoyltrifluoroacetate has been performed. Techniques are proposed for improving the agreement of the results of the simultaneous flurometric determination of the components of a mixture that are based on utilizing the different conditions for exciting fluorescence and the solvatochromic effect.
