摘要：

Paracetamol oxidation from aqueous solutions is studied by means of ozonation and H2O2 photolysis. Both oxidative systems are able to destroy the aromatic ring of the substrate with a partial conversion of the initial carbon content into carbon dioxide. For the adopted experimental conditions mineralization degrees up to 30% and 40% are observed with ozonation and H2O2 photolysis, respectively. Main reaction intermediates and products are identified for both systems by HPLC and GC-MS analyses and a kinetic characterization is achieved.. (C) 2002 Elsevier Science Ltd. All rights reserved.
