Photocatalytic degradation of 3-chloropyridine in the homogeneous (photo-Fenton) and heterogeneous (TiO2) phase was studied using both UV and sun light. Complete mineralization was achieved in both cases though times required in photo-Fenton process were ca. 5 times shorter under our experimental conditions. Results found at lab scale (solar simulator) were successfully extrapolated to a larger scale (30L) thus evidencing the validity of the method for treatment of waters polluted with this kind of chemical. Toxicity tests (Vibriofischeri)showed that some intermediates more toxic than 3-chloropyridine were formed as reaction proceeded.
