THE ROLE OF VITAMIN B6 IN THE CHEMICAL SELF-PURIFICATION PROCESSES OF AQUATIC SYSTEMS

Water resources can constantly renew themselves due to their self-purification capacity, but anthropogenic activities reduce the intensity of these self-purification processes. One of the organic substances present in water is vitamin B6, which is present in surface waters as a result of biological processes in water bodies or as a result of anthropogenic impact. So, the changes in vitamin B6 were examined using test systems that included substances involved in the self-purification of natural waters: dissolved oxygen, hydrogen peroxide, and copper (II) ions. Analysis of the results obtained shows that vitamin B6 efficiently degrades by reacting with dissolved oxygen in the presence of copper ions. This indicates that the substrate is not persistent and can be easily removed from the aqueous environment.
