Description	A sample of humic acid prepared from parental lignite and seven regenerated humic acids prepared from oxidized ones were extracted from South Moravian lignite. First, the samples were tested for their stabilities and degradabilities using thermogravimetry. It was shown that oxidation of lignite in static reactor at 85 C produced regenerated humic acids with an increasing content of labile part. The dependency of labile content was exponential-like and reached a constant value after 240 hours of oxidation. Increasing content of labile part in regenerated humic acids was also confirmed by measuring of heat accompanying the thermo-oxidative degradation using differential scanning calorimetry.The previously reported increase in number of ester bonds and the character of surface of prepared humic material was evaluated by moisture uptake measurement. Using thermogravimetry, the determination of the content of moisture adsorbed on the surface of humic samples after 21 days was carried out.
