Time-Resolved Fluorescence Spectra of Different Soil Humic Acids and Standard IHSS Elliott Soil
Popis výsledku v původním jazyce
The aim of this work was study structure and dynamics of different soil humic acids (HAs). Object of our study were three samples HAs which were isolated from sandy soil ? Arenosols (locality Ratíškovice, Czech Republic), Chernozem ? Haplic Luvisol (locality Praha-Ruzyně, Crop Research Institute, Czech Republic) and standard HA Elliott Soil (1S102H). Isolation of soil HAs were performed according to the procedure recommended by the International Humic Substances Society (IHSS). All samples of soil HAs were characterized by Steady-State and Time-Resolved Fluorescence Spectroscopy. Emission wavelength dependent fluorescence decays are used to construct Time-Resolved Fluorescence Spectra (TRES) of soil humic acids, which are useful to obtained informationon the excited state kinetics and heterogeneity of emissive species in a system. Time resolved fluorescence spectra (TRES), plotted as fluorescence intensity vs. wavelength, were constructed using alfai (wavelength) and taui (wavelength)
