A simple method of discrimination for the molecules of humic acids (HA) with respect to their dispersion states is proposed. The method is based on non-uniformity of the contour of HA luminescence spectra and involves the determination dependence of the position of maximum in the fluorescence spectrum
obs on the wavelength in the maximum of fluorescence excitation spectrum
or determination of the dependence of
on
obs. The applicability of the method is demonstrated with several samples of aqueous solutions of HA.
