The article deals with the study of factors participating in the extraction of humic acids from plant substrates under the action of electric discharges. Using the example of the electric discharge treatment of the peat-water suspension, it was demonstrated that the main factor affecting the intensity of extraction is the degree of the solid phase of the biosubstrate-water suspension grinding, which depends on the pressure amplitude at a distance of the inner radius of the chamber and the number of discharge pulses. Experimental studies have shown that the amount of chemical reagents (alkalis) commonly used in the extraction of humic acids from peat can be significantly reduced due to the appearance of radicals and peroxide compounds in the peat-water suspension during the action of an electric discharge. The perspectives of a non-thermal electric discharge method for intensifying the extraction of humic acids from biosubstrates are determined.
