The photocatalytic degradation of a macrolide (tylosin) has been studied using immobilized titanium dioxide as photocatalyst in a laboratory reactor under UV illumination (365 nm). The degradation of the antibiotic and of the reaction intermediary product was monitored by UV spectrophotometry and HPLC. Three photocatalysts (P25 from Degussa and PC105 and PC500 from Millenium) immobilized on glass plates were compared. A slightly better degradation was obtained with P25. Then the tylosin degradation kinetics were investigated with the P25 photocatalyst. The kinetic model of Langmuir-Hinshelwood is satisfactorily obeyed at initial time and in the course of the reaction. Adsorption and apparent rate constants were determined. These results suggest that, although an intermediary by-product was detected during the reaction, complete degradation of tylosin can be achieved, which confirms the feasibility of such a photocatalytic treatment for tylosin elimination from wastewater.
