Popis: In this work, the efficiency of direct photolytic and photocatalytic degradation of thiotriazinone, stable hydrolysis product of antibiotic ceftriaxone, was examined. The efficiency of photocatalytic degradation of 0.05 mmol/dm3 thiotriazinone solution was investigated using commercially available TiO2 Hombikat catalyst under simulated solar irradiation, as well as in the absence/presence of ammonium persulfate ((NH4)2S2O8) as electron acceptor. It was found that the optimal conditions for photocatalytic degradation of thiotriazinone were: catalyst loading 1.0 mg/cm3 of TiO2 Hombikat, electron acceptor 3 mmol/dm3 of (NH4)2S2O8 solution, and pH 7.6. Under the stated conditions 76.0% of thiotriazinone was degradated after 60 min of irradiation. The kinetics of degradation was followed by UFLC-DAD technique.
