It was found that the rate of oxidation reaction increases with increasing concentration of H2O2, because that H2O2 promotes the process of self-purification of the aquatic environment, and Cu2+ negatively influences, because that it forms a complex compound and is difficult to destroy.rocomplexul vitaminei Bautopurificare chimicăsisteme acvaticeArticle
