摘要

The degradation of Ketoprofen (KET) treated by ionizing technologies in aqueous solutions was investigated. The degradation efficiency exceeded 90% at doses less than 10 kGy for the lowest concentrations of KET and decreased with the increase of initial concentrations, requiring higher doses. The degradation kinetics followed pseudo-first order model. The electrical energy (EE/O) values, depending on the initial concentration of KET, ranged between 2.5 and 4.4 kWh/m3/order. Electron paramagnetic resonance (EPR) spectroscopy revealed the generation of quinones and carboxyl as main generated radicals. These results highlight the potential of ionizing technologies as effective process for removing emerging contaminants.
