Abstract
The paper discusses the decomposition mechanisms of hydrogen peroxide (HP) under the action of light, with the involvement of metal ions and their coordination compounds, as well as the participation of hydrogen peroxide in the peroxidase oxidation of various chemical substances. It is shown that these reactions are accompanied by the formation of partial charge transfer complexes and other short-living species as intermediates. Water self-purification capacity following the chemical way is discussed. New indicators for estimating the quality of natural water bodies have been proposed. HP plays an essential role in strengthening the immune system of living organisms, serving in the fight against various diseases, including COVID-19. In this regard, a kinetic model is proposed to evaluate and predict viral infections. We have experimentally demonstrated that HP can find broad applications in agriculture, specifically, in seed treatment, plant growth acceleration, the food industry, etc.
