Abstract:	Photo-induced advanced oxidation under 172 nm of paracetamol (PCT) and its by-products (BPs) was investigated. The evolution of Total Organic Carbon (TOC) as well as of PCT and relative BPs degradation, was followed. The treatment was compared with Fenton and photo-Fenton processes. It was possible to conclude that complete mineralization is feasible with photo-induced advanced oxidation. TOC conversion reached higher values under 172 nm while showed to reach an asymptotic value when Fenton and photo-Fenton Process were performed, even for high oxidant:contaminat ratios. All the investigated Advanced Oxidation Processes (AOPs), allowed attaining the elimination of the selected pollutant, but Fenton and photo-Fenton processes showed a faster decrease of both PCT and BPs, with a maximum total removal time for PCT of 15 min.
