Arsenic is a widespread contaminant in the environment. The intake of water containing high concentration of arsenic gives serious effects on human health, such as skin and lung cancer. In the European Union, and in Italy, the arsenic limit in drinking water is 10 µg/L. Several treatments are available for arsenic removal. For some processes the removal yields can be improved after the oxidation treatment. Most full scale applications are based on conventional oxidation processes but, if water contains arsenic and organic refractory contaminants, the Advanced Oxidation Processes could be considered. The aim of this work was to investigate the effectiveness of the arsenic oxidation using hydrogen peroxide, UV radiation and their combination in distilled and in real water. Some tests were performed on real groundwater polluted with arsenic and Terbuthylazine (TBA). Good arsenic and TBA oxidation yields can be reached in presence of H2O2 combined with a high UV radiation dose.
