Study of lignite humic acids by modern spectroscopic methods

Popis výsledku v původním jazyce

Humic substances (HS) especially humic acids (HA) are natural organic compounds arising by chemical and biological decomposition of organic matter (plant and animal tissues) and synthetic activity of microorganisms. Humic substances are among the most widely distributed organic materials on the Earth. Of course occurring in brown coal (Leonardites) and lignite, peat, soils, sediments and some other materials. Humic acids represent very important part of organic matter (OM) in lignite. Lignite contains ahigh proportion of humic acids, which amounts to 80 %. Object of our study was lignite humic acid and standard HA Leonardite (1S104H). Humic acid was extracted from South-Moravian lignite from the mine Mír in Mikulčice, Czech Republic. The lignite HAs were isolated according to the standard IHSS extraction method. Humic acids were characterized by elemental analysis, ultraviolet-visible spectroscopy, infrared spectroscopy and fluorescence spectroscopy. Ratios E2/E3 and E4/E6 (humificati
