Elemental analysis, FTIR and 13C NMR of humic substances isolated from forest soil

Popis výsledku v původním jazyce

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). The humic and fulvic acids were characterized and compared using chemical methods and spectroscopic techniques, including Fourier transform infrared (FTIR) and liquid-state 13C nuclear magnetic resonance (13C NMR). Infrared spectroscopy is a useful technique in characterization of structure, functional groups and formation modes of HS. 13C NMRspectra of soil HS were obtained with a Bruker Avance III NMR spectrometer at an observation frequency of 125.8 MHz for 13C. The approximate number of scans was 25.000. For data analysis, the spectra were divided into chemical shift regio
