UDK: 631.417
Annotation:
The elemental analysis of humic substances extracted from oxidized Ulaan Ovoo coal was conducted. The ash and moisture content, heat of combustion and structural characteristics of the humic acids and their fractions were determined, brutto-formula were presented. Humic acids selected by nitric acid oxidation have the highest yield and a high degree of oxidation
Keywords:
