NMR Spectroscopy of Humic Acids Obtained by Mechanochemical Treatment of Plant Raw Material in Water-Alkaline Media
Humic acids (HA) obtained by the mechanochemical processing of peat and saw wastes at Khanty-Mansiysk Autonomous Okrug were studied for the first time by means of <sup>13</sup>C NMR spectroscopy. Differences in the functional composition of the resulting humic acids depending on the type of base used and the chemical composition of the secondary plant raw material were revealed. The reasons of the increased physiological activity of humic acids obtained as a result of sanitation of the secondary plant raw material in water-alkaline media were established.
