Original Abstract

Humic acids (HA) isolated from lignite and five typical soil types in south Moravia region were characterized by elemental analysis, FTIR, SFS and 13C NMR spectral methods. Obtained results showed the highest aromaticity degree and mature of lignite HA and Modal Chernozem HA. On the basis mainly on 13C NMR spectra, Cambisol HA is substantial younger and contained significant more aliphatic compounds in comparison to Modal Chernozem and Lignite HA. FTIR spectra divided isolated HA into two groups. The first group included lignite HA, Modal Chernozem, Haplic Luvisols and Gleyic Stagnosol HA. The second group included Fluvi-Eutric Gleysol and Eutric Cambisol HA. All samples had the same main fluorophore peak at exc./ em.=468/488 nm. Correlation between RFI indexes and fractional composition of HS was found.
