THE COMPOSITION OF ORGANIC SUBSTANCES AND HUMIC ACIDS IN THE PEAT BOG OF BALANAK (GORNY ALTAI)
The paper is devoted to the identification of the composition of structural fragments of humic acids (HA) extracted from the peat in the peat bog of Balanak. The alkyl elements predominate in the composition of HA, and the amount of oxygen-containing functional groups and phenolic fragments is reduced. The identified characteristics of the composition of HA are connected with the slow processes of peat formation in the North-Eastern Altai. It is shown that with the increase of the degree of the peat decomposition in humic acids the degree of aromaticity increases, and the amount of carbohydrate and alkyl fragments decreases.
