| 1 | O_(3) based advanced oxidation for ibuprofen degradation显示文摘The degradation of the anti-inflammatory ibuprofen(IBP)was evaluated by several advanced oxidation processes.IBP was treated by single ozonation and oxidation with hydrogen peroxide(H_(2)O_(2)),as well as a combination of these treatments.In order to improve the efficiency,the presence of catalysts such as original carbon nanotubes,labelled as CNT,and iron oxide supported on carbon nanotubes,named as Fe/CNT sample,was considered.The evolution of IBP degradation,mineralization and toxicity of the solutions was assessed.The formation of intermediates was also monitored.In the non-catalytic processes,IBP was faster removed by single ozonation,whereas no significant total organic carbon(TOC)removal was achieved.Oxidation with H_(2)O_(2) did not present satisfactory results.When ozone and H_(2)O_(2) were combined,a higher mineralization was attained(70%after 180 min of reaction).On the other hand,in the catalytic processes,this combined process allowed the fastest IBP degradation.In terms of mineralization degree,the presence of Fe/CNT increases the removal rate in the first hour of reaction,achieving a TOC removal of 85%.Four compounds were detected as by-products.All treated solutions presented lower toxicity than the initial solution,suggesting that the released intermediates during applied processes are less toxic. | Vitória M.Almeida Carla A.Orge M.Fernando R.Pereira O.SaloméG.P.Soares | 2022 | Chinese Journal of Chemical Engineering2022，35，2： | 0 |
