The present work aims at analyzing the degradation of the drug Clonazepam (CZP), one of the best-selling controlled drugs in the world and a possible emerging contaminant of surface and wastewater. Compound degradation was performed by UVC photolysis of hydrogen peroxide, photo-assisted Fenton reactions (Photo-Fenton) by UVA, UVC lamps, and solar radiation, as well as by the H2O2/Iron Oxides System for comparison purposes. All analyses were conducted by high performance liquid chromatography (HPLC) with UV detector. The results reached conversions above 85 percent in most of the experiments and indicated the kinetics, mostly, with apparent order close to 2 and k equal 0.95 mg. L-1. min-1 in Photo-Fenton UVC and k equal 0.02 mg.L-1.min-1 in H2O2/Iron Oxides. In addition, toxicity analysis was carried out using lettuce seeds for H2O2/Iron Oxides, UVC photolysis and UVC lamp Photo-Fenton, with growth inhibition values of up to 44 percent.
