This paper is devoted to the study of the chemical transformations of vitamin B2 (riboflavin) in aquatic systems and its impact on the chemical self-purification processes of natural waters. The kinetics of the processes were monitored based on the vitamin concentration, determined by a direct spectrophotometric method at a wavelength of 444 nm. The research results demonstrated that under natural water conditions, vitamin B2 is stable, does not undergo oxidation by dissolved oxygen and hydrogen peroxide, and does not remove Cu(II) ions from their hydrochemical cycle by forming complex compounds. At the same time, riboflavin undergoes direct photolysis and generates reactive oxygen species, a phenomenon that has a positive impact on the self-purification processes and the redox state of the waters.
