Abstract
Changes of the quantitative and qualitative characteristics of peat components (bitumen, lignin, cellulose, humic acids) under cavitation action of aqueous alkaline media are considered. It was demonstrated that the cavitation treatment of peat in alkaline solutions involves the structural rearrangement, changes of separate fragments of macromolecules. As a result, additional amount of humic acids is formed. To obtain humic acids, it is preferable to use the aqueous solution of ammonia as the base. In water-ammonia medium, nitrogen fixation occurs with the participation of all the components of humate–carbohydrate complex.
