Rezumat

In this work are presented the studies on the photochemical transformations of TU (thiourea) and Cys (cysteine) with the addition of Cu(II) or Fe(III) ions to the system. So both thiols, TU, and Cys, have been subjected to induced photolysis with OH radicals, generated during irradiation of H2O2 with different artificial light sources in the presence of the Cu(II) and Fe(III) ions. Based on the results obtained, it was found that when Cu(II) or Fe(III) ions are added to the system, the oxidation rate of the thiols goes up a lot. It has been found that TU and, even more effectively, Cys bind the ions of the studied metals into stable complex compounds. It has been shown that the oxidation rates of the thiols depend also on the irradiation sources' radiation intensity and emission spectrum.
