ВЛИЯНИЕ ОКИСЛЕНИЯ РАСТИТЕЛЬНЫХ ОСТАТКОВ ПЕРОКСИДОМ ВОДОРОДА В ПРИСУТСТВИИ СЕРНОЙ КИСЛОТЫ НА СОСТАВ И ФУНКЦИОНАЛЬНЫЕ СВОЙСТВА

Background. Тhe development of technologies for processing organic resources, including plant residues, into organic and organomineral fertilizers and their application is relevant. Purpose. Studying the effect of hydrogen peroxide oxidation of plant residues in the presence of sulfuric acid on the composition and functional groups of organic substances. Methodology. The study of the influence of hydrogen peroxide oxidation of plant residues in the presence of sulfuric acid on the composition and functional groups of organic substances is carried out by determining the elemental composition of the organic part of the original plant material and oxidation products, determining the functional groups, graphostatic and IR spectroscopic studies of the original plant material and oxidation products. Originality. For the first time, the degree of oxidation and the kinetics of transformation of plant substances into extractive substances extracted by 1% sodium hydroxide solution were studied, the changes in the chemical composition and functional groups of the formed organic acids during the oxidation of plant residues using hydrogen peroxide in the presence of sulfuric acid were determined. Findings. The elemental composition of the original and oxidized plant residues, the extractive substances extracted by 1% sodium hydroxide solution, and the residual plant residue after extraction of the extractive substances, as well as the content of functional groups in them, have been determined. It has been shown that as a result of the oxidation of plant substances in the latter, the content of oxygen and active functional groups increases, both in the shroud itself and in its extractive substances, including extractive substances.
