| description | Aqueous solutions of lincomycin were irradiated with UV light in
homogeneous and heterogeneous systems. Lincomycin disappeared in
both systems but the presence of TiO2 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
TiO2 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. |
