ChimieTags : Paracétamol Aspirine Photodégradation Radicaux hydroxyle Goethite Fenton Paracetamol Aspirin Photodegradation Hydroxyl radicals ????????????? ???????? ?????? ?????? ???? ??????????? ?????? Index. décimale : 540 Chimie et sciences connexes Résumé : The photodegradation of two pharmaceuticals (PP), paracetamol (PC) and aspirin (ASP), induced by an iron (III) oxyhydroxide (Goethite) was studied in aqueous solution in heterogeneous phase. The phototransformation of the substrates was followed by spectrophotometry and HPLC in various mixtures namely: PP-Goethite, PP-Goethite-H2O2 and PP-Goethite-carboxylic acid. In absence of light both substrates showed different behavior with regard to Goethite in aqueous solution. Indeed, no interaction was observed in the case of the PC whereas a particular reaction was highlighted in the case of the ASP. Under irradiation, photodegradation of PP induced by Goethite shows slow kinetics and is dependent on several parameters such as pH, substrate concentration and catalyst. Fe (II) formed exclusively in the ASP-Goethite mixture shows the photocatalytic dissolution of Goethite. The mechanistic study reveals that hydroxyl radicals are not involved in the photocatalytic process of PC, however they govern on the photodegradation mechanism of ASP. The addition of hydrogen peroxide in the PP-Goethite mixture improves significantly the rate of disappearance of the substrates following a large production of ●OH radicals generated by a heterogeneous photo Fenton reaction. Different parameters have been studied, the effect of pH, as well as the concentration of H2O2.
The addition of carboxylic acid to the PP-Goethite system has also been studied and shows that oxalic acid has the most important photoactivity following the involvement of the eterogeneous like-Fenton process resulting from the photoreductive dissolution of the complex surface formed between Fe (III) of Goethite and oxalic acid. The following of the mineralization shows that the life of intermediates reaction is much greater than the starting product. In order to verify the feasibility of the photochemical process in the environment, the same systems were studied under solar irradiation. The results show that such systems operate with kinetics of the same order as those observed in artificial irradiations. These results provide some knowledge about the fate of PP in the aquatic environment as well as the photocatalytic treatment with oxy (hydroxides) of Fe (III). These results are very promising for the application of this system under pH conditions close to those met in the environment.

ChimieTags : Photodégradation La GOE Dérivés phénoliques Radicaux hydroxyle Fenton Photodegradation GOE Phenolic derivatives Hydroxyl radicals ?????? ?????? GO?????? ??????? ? ???? ??????????? ????? Index. décimale : 540 Chimie et sciences connexes Résumé : The effectiveness of Goethite (GOE) in inducing the photodegradation of organic pollutants under artificial and solar irradiation in a heterogeneous medium and in aqueous solution was the main objective of this study. We used four organic pollutants of the phenol family (RP, BBP, BCP, phenol) whose chemical structure differs depending on the substitute nature. In the absence of light and in our experimental conditions, two distinct behaviors were observed as a function of the pollutants studied during the mixing of the GOE-substrate. Indeed, in the Phenol-GOE mixture, no interaction was observed whereas a slow reaction, in the presence of the GOE, was demonstrated with RP, BBP and BCP. This interaction can be attributed to a low adsorption of the substrate on the GOE in the following order: BCP (15%)> BBP (12%)> RP (5%)> Phenol (1%), and this phenomenon is optimal in acidic medium. The addition of H2O2 accelerates the thermal process in RP-GOE system while an inhibitory effect was observed for the other two substrates (BBP, BCP) in the presence of GOE. The presence of carboxylic acids in the substrate-GOE system has shown that oxalic acid has a positive effect on the kinetics of BCP and RP eliminations under our experimental conditions. Under irradiation at 365 nm, the photodegradation of these pollutants by the GOE, was characterized by slow kinetics and seems to be dependent on several parameters such as the pH, the concentration of the substrate, the catalyst concentration, the oxygen and the molecular structure of the substrates. The mechanistic study reveals that the radicals HO • do not intervene in the mechanism of degradation of the phenol on the other hand they govern the reaction in the case of RP, BBP and BCP. The addition of H2O2 in a GOE suspension significantly improves the rate of photodegradation due to additional production of HO• radicals generated by the Fenton photo process. Different parameters have been studied to optimize this process. In the same way, the efficiency of the photochemical process is improved by the presence of carboxylic acid in a GOE suspension following the involvement of the heterogeneous like-Fenton process resulting from the reductive photo dissolution of the surface complex formed between the Fe (III) Goethite and oxalic acid. In order to verify the feasibility of the photochemical process in the
environment, the same systems were studied under solar irradiation. The results show that such systems operate with kinetics of the same order as those observed in artificial irradiation, which can reduce the energy costs of the photochemical process.Diplôme : Doctorat en sciences En ligne : ../theses/chimie/BEL7350.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=11000 Contribution à l’étude de la dégradation photochimique de polluants organiques par les oxyhydroxydes de Fe (III) en solution aqueuse en phase hétérogène.

(III) – ?????????) DCO ??????? ??????Index. décimale : 540 Chimie et sciences connexes Résumé : In this study we have used dimethylphenols (xylenol) as models pollutants to show the effectiveness of the natural hematite (Fe2O3 natural) on the photocatalytic processes in heterogeneous environment.
The degradation of 3,5-dimethylphenol by Fenton and photo-Fenton processes was investigated, starting with the study of its photolysis at 254 nm and by H2O2/UV process.
Different physico-chemical parameters (concentrations of H2O2, Fe2+ and the pH) were tested in order to optimize the efficiency of Fenton process for degradation of 3,5-DMP. A Comparison of the performance of mineralization by different processes studied (Fenton and photo-Fenton) has shown that 70% and 80% of DOC removal was obtained after only 4 hours of photo-Fenton process at 365 nm and 254 nm respectively.
In the field of heterogeneous photocatalysis, a naturally occurring mineral was used. It was characterized by XRD, BET, IR and SEM. The XRD analysis showed the presence of 9 characteristic peaks attributed to hematite. Its photocatalytic efficiency was tested by the oxidation of 2,6-dimethylphenol (2,6-DMP). Photocatalysts based on iron (Fe2O3) have photocatalytic efficiency in the visible region. The results showed good efficiency under solar irradiation for the degradation of 2,6-DMP. Experiments carried at 365 nm required activation of the iron oxide with carboxylic acids. oxalic acid was the most effective carboxylic acid in terms of dissolution of natural iron oxide, and degradation of 2,6-DMP. Fe (III) - oxalate complex produce Fe2+ species by the photo-reduction of Fe3+ species and also lead to the
formation of hydrogen peroxide which reacts with Fe2+ to give •OH (Fenton reaction). We have optimized the experimental parameters affecting the degradation rate (oxalic acid concentration, pH, O2, temperature, inorganic ions ...) and propose a mechanism of degradation. The abatement rate of COD was 85% obtained for a treatment time of 14 hours in natural iron oxide - oxalate system under irradiation at 365 nm, demonstrating the ability of this technique to clean up effluents loaded with organic matter. The coupling of the system with the solar light has increased the rate of degradation of 2,6-DMP to 92% after 5 hours.
The use of natural iron oxide alone or in the presence of oxalic acid seems to be favored under solar irradiation which can reduce energy costs, especially in a country like Algeria.

(GOE) (like Fenton) ????????? ?????? Index. décimale : 540 Chimie et sciences connexes Résumé : Our objectives in this thesis were to demonstrate the effectiveness of Goethite (GOE) in the
amoxicillin (AMX) photodegradation process under artificial and solar irradiation by different
systems, as well as the optimization of experimental parameters affecting the rate of the
degradation. Different analytical methods have been used in the characterization of AMX and
GOE. In the absence of light, the transformation of AMX was studied in different mixtures
(AMX-GOE, AMX-GOE-H2O2 and AMX-GOE-Carboxylic Acid). An interaction between
AMX and GOE was demonstrated; H2O2 significantly improved the degradation of AMX
while no effect was mentioned in the case of the presence of carboxylic acids. Under
irradiation and in the absence of GOE, AMX was found to be photolysed at 254 nm and
refractory to photolysis at 365 nm (monochromatic and polychromatic); this is due to the
overlap between the absorption spectrum of AMX and the light source.
The photodegradation of AMX by heterogeneous photocatalysis in the presence of GOE has
been studied. Results show that the photodegradation is dependent on several parameters such
as pH, substrate and catalyst concentration. The use of free radical inhibitors has shown that
the reaction mechanism is dominated by •OH radicals where oxygen plays an important role.
The addition of H2O2 to the solution improves the degradation of AMX and increases its rate
of mineralization in terms of chemical oxygen demand. The degradation is effected by the
contribution of the •OH radicals and also by oxidation on the surface of GOE. The AMXGOE-carboxylic acid system has been tested, among the used acids, oxalic acid was the only
one that showed a photo-activity. By comparing the degradation kinetics of AMX in natural
and artificial light in the three studied systems, it is found that the degradation rate is higher
under solar irradiation.
