Change in content and properties of humic substances during their consistent extraction from peat and brown coal
Abstract
The results of changes in the composition and properties of humic substances during their sequential extraction from peat and brown coal of various origin are presented. When extracting from peat raw materials during the first treatment, no more than 30 masses are extracted % of the content of humic substances. This figure is about 50 masses are extracted % for brown coal. It has been shown that depending on the raw material, the extraction of humic substances occurs unevenly. The results of elemental and thermal analyzes did not reveal significant differences in the structure of the fractions isolated sequentially from caustobiolites.
