Chemical crosslinking of lignite humic acids
Original language description
The aim of this work was the modification of South Moravian lignite humic acids in order to obtain cross-linked materials with improved water retention capacity. The modification by formaldehyde was used and affinity to water, kinetics of hydration and water retention capacity of obtained products were studied by thermal analysis. It was observed that all the modified samples of humic acids had higher retention capacity in comparison with the parental humic material which means that the supramolecular structure of humic acids was cross-linked and the hydrogel system was formed.
