The advanced oxidation processes were examined toward the degradation of thymine (C₅H₆N₂O₂), a type of nucleic acid from the pyrimidine family. As observed, the photodegradation of thymine over TiO₂ photocatalyst was rapid and significant in aqueous solution under UV irradiation. Different parameters were studied, including the adsorption of thymine onto TiO₂ photocatalyst, the kinetics of degradation, and the effect of pH on the photocatalytic properties of thymine degradation. Additionally, the mineralization of the products obtained upon thymine photodegradation was studied. The disappearance and mineralization rates of thymine during the photocatalytic process were also compared and discussed. The mineralization of nitrogen was also investigated, and the identification of the intermediate products was established. Finally, electronic density calculations were used to propose possible chemical pathways for the photodegradation of thymine over TiO₂ photocatalyst under UV irradiation.
