comparative study of the degradation of sulfaclozine in uv/tio2, uv/k2s2o8, uv/tio2/k2s2o8 system
Résumé
Advanced oxidation processes (AOPs) are techniques based on the generation of highly reactive radicals used for the degradation of organic compounds. There are many AOPs such as heterogeneous photocatalysis using for instance, TiO2 as a catalyst or in situ chemical oxidation (ISCO) using oxidants such as persulfate which are widely used for water treatment. The different reactive species generated in each of these systems may react differently or similary with organic compouds. Moreover, water constituents effects may vary from a system to another. Thus, we aimed to compare the degradation of sulfaclozine in three systems: UV/TiO2, UV/K2S2O8 and UV/TiO2/K2S2O8, and to show the effect of water constituents in each of these systems.
