الملخص

This work aims to develop a combination of two advanced oxidation processes, the Fenton process and a non-thermal plasma generated by Glidarc discharge, to degrade completely two emerging pollutants of pharmaceutical origin: paracetamol (PCM) and diclofenac (DIC). The degradation and the mineralization of the molecules were studied using analytical techniques, chromatographic and measurement of pollution indicators: COD, TOC and HPLC.The treatments were applied separately and then coupled to evaluate the synergy between the two processes: (i) the Fenton process resulted in complete removal of PCM and DIC but low mineralization rates of 34% and 48.6% were obtained respectively for PCM and DIC; (ii) the GAD method applied with different discharge times t* ranging from 0.5 to 60 min gave a degree of mineralization not exceeding 21% for both pollutants and whatever the discharge time; and (iii) In the post-discharge mode the percentage of mineralization increased as a function of post-discharge until reaching a stable value (≈ 52%). The HPLC technique indicated the persistence of some by-products for the three cases of Fenton process treatment, direct GAD discharge and post-discharge mode.The Coupled process plasma GAD -Fenton process has given a high degree of mineralization (> 92%) and complete elimination of aromatic intermediates through post-discharge.
