Original Abstract

The aim of this work was study chemical composition and structure of soil humic substances (HS). Object of our study were three samples HS which were isolated from Humic Podzol (locality Krkonoše, Czech Republic). Isolation of HS was performed according to the procedure recommended by the International Humic Substances Society. All samples of HS were characterized by elemental analysis (EA), ultraviolet-visible spectroscopy (UV/Vis), infrared spectroscopy (FTIR) and steady-state fluorescence spectroscopy. Absorption coefficients (EET/EBz, E2/E3 and E4/E6) of HS were calculated from the absorbance values. Fluorescence coefficients (Milori index and Zsolnay index) of HS were calculated from the area of the emission spectra.

Keywords

humic substances, spectroscopic methods, absorption coefficients, fluorescence indexes, steady-state fluorescence spectroscopy
