Spectroscopic and Structural Analysis of Humic Substances Isolated from Forest Soil Humic Podzol - Locality Krkonoše, Czech Republic
Original language description
The aim of this work was study chemical composition, chemical properties and humification degree of different soil humic substances (HS). The object of our study were three various samples of HS. HAs and FA were isolated from forest soil Humic Podzol (locality Krkonoše, Czech Republic). Isolation of soil HS was performed according to the procedure recommended by the International Humic Substances Society (IHSS). All samples of soil HS were characterized by elemental analysis (EA), ultraviolet-visible spectroscopy (UV/Vis), Fourier transform infrared spectroscopy (FTIR) and steady-state fluorescence spectroscopy. Absorption coefficients (EET/EBz, E250/E365 and E465/E665) of soil HS were calculated from the absorbance values. Infrared spectroscopy is a useful technique in characterization of structure, functional groups and formation modes of HS. For the fluorescence experiments the final concentration of the HS was adjusted to 10 mg/dm3. The pH-value of the samples was adjusted to seven
