description | <p>Aqueous solutions of lincomycin were irradiated with UV light in homogeneous and heterogeneous systems. Lincomycin disappeared in both systems but the presence of <mml:math> <mml:mrow> <mml:msub> <mml:mrow> <mml:mtext>TiO</mml:mtext> </mml:mrow> <mml:mtext>2</mml:mtext> </mml:msub> </mml:mrow> </mml:math> noticeably accelerated the degradation of the antibiotic in comparison with direct photolysis. The rate of decomposition was dependent on the concentration of lincomycin and followed a pseudo-first-order kinetics. Photolysis involved only the oxidation of lincomycin without mineralization. Differently, the treatment with <mml:math> <mml:mrow> <mml:msub> <mml:mrow> <mml:mtext>TiO</mml:mtext> </mml:mrow> <mml:mtext>2</mml:mtext> </mml:msub> </mml:mrow> </mml:math> and UV light resulted in a complete mineralization of the antibiotic. The degradation pathways involved S- and N-demethylation and propyldealkylation. The mineralization of the molecule led to the formation of sulfate, ammonium, and nitrate ions.</p> |
