| description | This study evaluated the degradation potential of the drug Sertraline by means of photocatalysis processes, with the combination of ultraviolet (UV) energy and different semiconductors. Photocatalytic assays were performed in 10 mL of Sertraline solutions containing 10 mg L-1, added to the different semiconductors (10 mg). The samples were submitted to radiation (UV) in five degradation times (0, 5, 10, 30, 60 and 120 minutes). The determination of Sertraline concentration was by high performance liquid chromatography with UV detection. (HPLC-UV). Sertraline degradations of 51%, 74%, 75% and 83% were determined after application of photolysis, photocatalysis TiO2, TiO2-Mn and TiO2-B, respectively. Thus, the higher efficiency in the degradation process was determined for the boron-doped TiO2 semiconductor. Thus, the application of the photocatalysis process can be of great importance in the effluent treatment processes, and the insertion of doping agents can make semiconductors more active in photocatalysis processes. |
