Реферат:
Humic acids of brown coal before and after mechanochemical treatment under various conditions were studied by TG and DSC (carried out both in air and in an inert atmosphere, with the temperature range of 300-800 K), and gel permeation chromatography. The obtained data were used to calculate the values of the energy of activation and the thermal effects for each stage of thermal decomposition. Influence of mechanochemical treatment upon humic acids thermolysis stages was shown. Hypothesis of thermal stages chemical interpretation was proposed. The staged decomposition of humic acids includes the stages of decarboxylation of acid groups of various types. A change in the staging of decomposition is observed upon mechanochemical introduction of alkali into humic acids, associated with the conversion of acid groups to the salt form. © Published under licence by IOP Publishing Ltd.
