Název v původním jazyce

Total Luminescencence spectra of lignite humic acid and sodium humate

Popis výsledku v původním jazyce

The aim of present work was to investigate differences in fluorescence spectral characteristics between lignite humic substances. According to our experience the relative intensity of fluorescence (RFI) of the maximum can differ. Lignite humic acids wereisolated from lignite (locality of Mikulčice, South Moravia of Czech Republic) and Lignite sodium humate (HU) was prepared from lignite humic acid solution by titration with HCl solution to pH7. Fluorescence measurements were done on spectrofluorimeterAminco Bowman. TLS spectra were corected. Fluorescence spectra of lignite humic acid and sodium humate are different. TLS-contour plot of lignite humic acid exhibited two major peaks at ex./ em. =395/490 nm, 355/458 nm, two main fluorophores. sodium humate have higher relative intensity of fluorescence and second peak is shifted to the longer wavelength (red shift). In accordance with literature, fluorophores of lignite samples emits at wavelengths that Leonardite humic acid standard (IH
