Testo completoIn the first part of this work, we explored the applicability of polypyrrole (PPy) as a photocatalyst for H2O2 production. Our results showed that PPy synthesized by radiolytic polymerization are very active for H₂O₂ generation under visible light. The influence of different parameters on H₂O₂ formation over PPy has been studied for the first time. Moreover, we studied the possible pathways for the H₂O₂ formation via scavenging experiments, showing that it predominantly proceeds via oxygen reduction. The decomposition and formation rate of H₂O₂ were also shown to be dependent on the catalyst concentration, pH and light intensity. Then we next studied the application of in situ H₂O₂ generation for water pollutant degradation. In this part, a new self-sustained photo-Fenton system for water treatment, that combines g-C₃N₄ or PPy, a known H₂O₂ synthesis photocatalyst, with a Ti-substituted Lanthanum Ferrite (LTFO) photo-Fenton catalyst, to enhance the pollutant degradation under solar light. Using phenol as model pollutant, we show that the g-C₃N₄/LTFO or PPy/LTFO composite exhibits better catalytic activity. Characterization and analysis reveal that the synergistic interaction between the composite leads the catalyst to operate as photo-Fenton-type catalyst in the absence of any addition of external H₂O₂. The results demonstrate that using a g-C₃N₄/LTFO composite in the photo-Fenton reaction is a promising approach for efficient and sustainable water treatment free of external H₂O₂ at circumneutral pH. The study also opens avenues for further research in optimizing these types of composites for broader environmental applications. In addition, preliminary results on the utilization of g-C₃N₄@ZnO nanowires composites in H₂O₂ production are presented. Characterizations revealed that ZnO naanowires and g-C₃N₄@ZnO are successfully prepared and will be further tested for the desired applications. Our results showed that a simple PPy polymer is a candidate material for photocatalytic H₂O₂ generation and the concept of in-situ H₂O₂ generation using polymers for photo-Fenton process is an interesting concept for water treatment applications

Testo completoIn the current context, the elimination ways of sludge resulting from the wastewater treatment are subjected to social, sanitary and lawful constraints. Coupled processes, associating several technologies to conventional biological processes, are currently studied to reduce this production. The chemical processes of oxidation, in particular ozonization, seem to generate a high reduction ratio of sludge production (RSP). Concerning this objective, the hydrogen peroxide (H2O2) only was little studied whereas it presents a priori some advantages compared to ozone. The aim of this study is the characterization and the analysis of the effect of H2O2 on the sludge matter, as well as the performances of the coupling of a peroxidation system to an activated sludge system. The action of H2O2, in a closed reactor, leads to a high rate solubilization of particulate organic matter (measured as Particulate Organic Carbon) which depends on the temperature, tested between 60°C and 95°C. More than 85% of the POC of digested sludge is solubilized at 95°C compared to 20% for activated sludge. At 95°C, some operating conditions (initial pH, addition mode of H2O2, addition of Fe 2+ like catalyst) were varied in order to determine the favorable conditions to a high rate of POC solubilization, maximizing the effectiveness of H2O2 action. These conditions are: initial pH 8 and addition in one shot. The iron addition has not a visible effect on the H2O2 effectiveness. A little solubilization ratio of mineral matter from sludge is observed. Surprisingly, the consumption ratio of H2O2 is always constant whatever the solubilization ratio and for all of tested operating conditions. Thus, in addition of solubilization reactions, a H2O2 consumption for competitive reactions exists. Hypotheses on the action mechanisms were proposed, given the many possible complex reactions with H2O2. The coupling chemical- biological treatments by H2O2, was carried out in open reactors. The characterization of sludge production at the time of the combined biological-H2O2 treatments made possible to observe a reproducible RSP of 50% compared to the sludge reference production for an amount of 0,45gH2O2/gVSS. A mineralization of sludge is observed confirming the preceding results. An existing model was adapted to represent the evolution of the variables of combined processes. With this model the concentrations in COD of the effluent and VSS of the basin of activation are correctly represented. Nevertheless, it will be necessary to validate this model for other amounts of H2O2. The economic analysis of the process shows that the cost of sludge not produced by using H2O2, is prohibitive taking into account the current cost of the elimination of sludge. An optimization of the amount of H2O2 used, operating temperature but also of the capital costs is necessary to consider this process on an industrial scale

Testo completoHydrogen peroxyde is necessary to cellular proliferation but is toxic at high concentrations. Tumor cells are submitted to severe oxidative, close to toxic threshold, increasing their sensitivity to pharmacologic compounds able to increase intracellular concentration of hydrogen peroxide. Placlitaxel induces an early hydrogen peroxide accumulation which is significantly involved in its antitumoral effect, in vitro and in vivo. Mangafodipir, a superoxide dismutase (SOD) mimic, increases the hydrogen peroxide production in tumor cells and enhances the antitumoral effect of paclitaxel. Moreover, it is able the hematologic toxicity of paclitaxel in vivo. This differential effect of mangafodipir seems to be related to its dual activity, SOD and glutathione reductase, responsible for an antioxidant effect in non-tumoral cells
