Comparison of Thermal and Chemical Stability of Cu-humic Complexes

Popis výsledku v původním jazyce

This work is focused on comparison of thermo-oxidative and chemical stability of copper complexes with humic acids.The humic acid was extracted from South-Moravian lignite by standard alkaline extraction . The humic sample was used in two different forms: as solid powder and as hydrogel prepared by acidic precipitation of humate. Three various concentrations solutions of Cu2+ solutions were used for complexation of humic powder and gel, in order to study the influence of their initial concentration on both determined stabilities of the prepared complexes. Their chemical stability of wasassessed in term of Cu2+ ions release from the humic acid structure into two different extraction agents (MgCl2 and HCl solutions). Their thermooxidative behaviour was investigated employing thermal analysis (TGA).
