Název v původním jazyce

Study of humic acids by synchronous fluorescence spectroscopy

Popis výsledku v původním jazyce

Humic acids (HA) were isolated from South Moravia lignite by standard alkaline extraction (IHSS procedure). Were have also prepared samples of humates (NaHA) from lignitic humic acids. Samples of humates were dried or freeze dried. Synchronous fluorescence spectroscopy can be used for characterization of humic substances containing aromatic groups (phenoles, phenolates). For fluorescence measurement, Aminco Bowman Series 2 has been used for synchronous scan from 300 to 600 nm at room temperature. We havve used optimal setting between monochromators (??=?em.-?ex.= 20 nm), slit width 4 nm. Dried samples of HA were dissolved in sodium hydroxide and samples of humates were dissolved in water. One standard sample of Leonardite humic acid (ordere from IHSS)has been used. Optimal concentration of HA or NaHA was 0,01 g/l. Samples have been measured in Suprasil cuvette (1 cm). The best resolution was achieved using synchronous fluorescence spectra. We have obtained spectra with main peak at ab
