“…To remove BPA from polluted aqueous systems, several techniques such as ozonation [4], Fenton degradation [5], photocatalytic decomposition [6], electrochemical oxidation [7] and UV/H 2 O 2 oxidation [8] have been developed. However, conventional treatment processes may not produce suitable degradation results [9,10] or may require large amounts of chemicals and/or energy.…”

“…Like other AOPs such as photocatalysis [3], ozonation [4], catalytic wet air oxidation [5], electrooxidation [6], persulfate oxidation [7], cavitation [8] and the Fenton process [9], CWPO relies on the formation of highly oxidizing hydroxyl radicals (HO%), which subsequently serve as effective species for the destruction of most of the organic pollutants present in aqueous phase [10,11]. In CWPO, HO%are formed from the catalytic decomposition of hydrogen peroxide (H 2 O 2 ).…”

The role of cobalt in bimetallic iron-cobalt magnetic carbon xerogels developed for catalytic wet peroxide oxidation

A B S T R A C TThree magnetic carbon xerogels were developed by inclusion of iron and/or cobalt precursors during the synthesis procedure. The synthesized materials were tested in the catalytic wet peroxide oxidation (CWPO) of aqueous solutions containing 4-nitrophenol (4-NP) − a refractory organic model pollutant, under a water treatment process intensification approach. For that purpose, the experimental runs were performed with high pollutant load (5 g L, corresponding to a fixed pollutant/catalyst mass ratio of 2), atmospheric pressure, 50°C, pH = 3 and stoichiometric amount of hydrogen peroxide (H 2 O 2 ).The bimetallic magnetic carbon xerogel catalyst (CX/CoFe) was more active than each of the monometallic catalysts (CX/Fe or CX/Co). The better performance was explained in terms of a synergic association of factors: (i) the enhanced accessibility to the active iron species at the surface of CX/CoFe promoted by the simultaneous incorporation of cobalt, (ii) the ability of metallic Co to catalyse H 2 O 2 decomposition via hydroxyl radicals (HO%) formation, and (iii) the efficient reduction of Fe 3+ to Fe 2+ promoted by metallic Co on the surface of CX/CoFe. A 4-NP conversion of 98.5% was determined after 30 min of CWPO reaction. Leaching of the iron species in the bimetallic CX/CoFe was considerably reduced with relation to the monometallic iron catalyst. However, partial catalyst deactivation occurred due to lower stability of oxidized cobalt species. A detailed reaction mechanism is proposed for the surface catalytic reactions occurring over the CX/CoFe catalyst.

Three non-steroidal anti-inflammatory drugs (NSAIDs)-ketoprofen, naproxen and piroxicam-in both deionized (DI) water and surface lake water (SW) (Tallahassee, FL), were exposed to varying ozone treatment regimes or H 2 O 2 /O 3 advanced oxidation on the laboratory bench. Recently used biofilm-supporting granular activated carbon (BAC) was sampled from a municipal drinking water treatment facility (Tampa, FL, USA), and employed to determine the bio-availability of chemical intermediates formed in ozonated water. Advanced chemical analysis was used to identify oxidation by-products formed and combined with a bioanalytical tool to assess non-specific toxicity (Microtox assay). All 3 target pharmaceuticals were efficiently removed by different processes, with a lower NSAIDs removal yield observed in lake water compared to DI water experiments. The removal yields of ketoprofen, naproxen, and piroxicam improved with increasing ozone dose, H 2 O 2 /O 3 ratio and empty bed contact time (EBCT) with BAC. Ozonation with BAC filtration had a positive impact by reducing the initial ozone dose required to achieve > 90% removal of all 3 pharmaceuticals (when an initial ozone dose < 1 mg L -1 was combined with EBCT < 15 min). The toxicity evolution of the treated samples was monitored by Microtox bioassay. Ozone doses higher than 2 mg L -1 for 2 min contact time were optimal to reach the lower water samples toxicity with NSAIDs removal yields ranging from 95.5 to 99.0% in DI water and from 77 to 90% in SW. Also, higher ozone doses were not shown to remove the residual toxicity. In contrast, the BAC filtration hardly decreases the sample toxicity when an EBCT of 15 min was
