Influence of redox conditions and mechanical action on change in peat humic acid composition

Abstract

Mechanical action on humic acids is shown to result in change of their composition accompanying decrease in aromaticity degree and increase in oxygen-containing fragments. Mechanical treatment of peat in oxidizing conditions increases the efficiency of extracting water-soluble components and humic acids to the maximum. Structural parameters and functional composition of humic acid molecules change at peat treatment in the redox conditions depending on the conditions.
