Abstract
Composition of gas mixtures formed during the electrochemical (in the presence of H2O2) oxidation of the wastes of human vital activities and subsequent decomposition of carbamide remaining in solution after the oxidation of metabolites was studied. A principal possibility of the selective catalytic oxidation of ammonia evolved due to the decomposition of carbamide to form nitrogen oxides was demonstrated, for the purpose of obtaining the salts of nitric acid those are well assimilated by plants.
