The results obtained, confirm that diminishing of the content of H2O2 and OH radical causes the decrease of self-purification capacity of natural waters, inducing unfavorable conditions hydro-biota. It has been proved that the processes of peroxydase oxidation of substrates (hydroquinone and glyoxalic acid) under the influence of copper (II) ions catalysts the OH radicals a formed, while in the processes where iron (III) ions are used their formation does not occur. In the presence of the self-purification capacity of natural waters is decreasing. On the contrary, the presences of glyoxalic acid in natural water environments contribute to intensification of the processes self-purification through radicals. |
