Abstract:
A series of Fe2O3@LSF (La0.8Sr0.2FeO3−δ perovskite) core-shell materials (CSM) was prepared by infiltration of LSF precursors gel containing various complexants and their mixtures to nanocrystalline aggregates of hematite followed by thermal treatment. The content of LSF phase and amount of carboxyl groups in complexant determine the percent coverage of iron oxide core with the LSF shell. The most conformal coating core-shell material was prepared with citric acid as the complexant, contained 60 wt% LSF with 98% core coverage. The morphology of the CSM was studied by HRTEM-EELS combined with SEM-FIB for particles cross-sections. The reactivity of surface oxygen species and their amounts were determined by H2-TPR, TGA-DTG, the oxidation state of surface oxygen ions by XPS. It was found that at complete core coverage with perovskite shell, the distribution of surface oxygen species according to redox reactivity in CSM resemble pure LSF, but its lattice oxygen storage capacity is 2–2.5 times higher. At partial coverage, the distribution of surface oxygen species according to redox reactivity resembles that in iron oxide.

Abstract:
The results obtained show that, in a strongly complexing medium, mercury is oxidized to mercury(II) with the concomitant formation of more highly oxidized complexes like [Formula: see text] and [Formula: see text]. When the reactional medium is less strongly complexing, however, the formation of complexes with Hg(1) can be considered. This complicates the exploitation of titration curves resulting from the progressive transformation of the complexes of mercury(II) into complexes of mercury(I) by contact with metallic mercury. Compared to the behavior observed in numerous organic solvents, the behavior of these systems is not fundamentally different.

Abstract:
Combining the characteristics of rare earth extractants and water-soluble polymer complexants, a novel complexant phosphorylated chitosan (PCS) was synthesized by Kabachnik–Fields reaction with alkalized chitosan, dimethyl phosphonate, and formaldehyde as raw materials and toluene-4-sulfonic acid monohydrate (TsOH) as catalyst. The complexation properties of PCS and poly (acrylic acid) sodium (PAAS) for lanthanum ions in the solution were compared at the same pH and room temperature. In addition, the frontier molecular orbital energies of polymer–La complexes were calculated by the density functional theory method, which confirmed the complexation properties of the polymers to rare earths. The results indicate that the PCS has better water solubility compared with chitosan and good complex ability to rare earths, which can be used for rare earth separation by the complexation–ultrafiltration process.

Abstract:
Carbon coated micro/nanostructure FePO4composite materials were synthesized by hydrothermal methode, in which citric acid was used as both complexant and carbon resource. The dependence of synthesis process and complexant on the structure and morphology of composite materials were investigated by X ray diffraction (XRD) and scanning electronmicroscopy (SEM). The results showed that the sample consisted of dispersive microspheres with a quite uniform size distribution of 10μm through hydrothermal reaction at 130°C for 24h, when solution concetration was 0.03mol/L and pH value was nearly 2. After calcinated at 550°C for 3h, the microspheres were comprised of nanosticks, and their specific surface area can reach nearly 14 m2/g. Due to their micro/nanomicrosphere structure, the composite materials will benefit to the increase of lithium diffusion rate meanwhile preserve high tap density.

Abstract:
Plusieurs récepteurs moléculaires de cations métalliques, associant l'unité tétrathiafulvalène à un site complexant ont été synthétisés. L'optimisation structurale par rapport aux systèmes initiaux concerne à la fois : le site électroactif (l'utilisation d'un squelette bis-pyrrolo TTF permet ainsi d'éviter les problèmes d'isomérisation Z/E rencontrés dans les dérivés rétrathio TTF) ; l'unité complexante (la préparation de macrocycles variant tant par leur taille (chaîne polyoxaéthylène) que par leur nature (chaîne polyéther, diaza-tétraoxa-18-couronne, dioxocyclame) doit permettre le piégeage d'autres cations métalliques). Ces synthèses ont pu être menées à bien en utilisant des techniques de haute-pression ou de haute-dilution. Les propriétés complexantes de ces molécules hôtes ont été évaluées à l'aide de différentes méthodes (spectrométrie de masse, RMN, spectroscopie UV-visible et voltammétrie cyclique). On peut notamment souligner les propriétés complexantes sans précédent en série TTF, d'un de ces récepteurs à l'égard de Ba2+ et Pb2+. Le caractère modulable des constantes de complexation en fonction du potentiel électrochimique appliqué a pu être démontré par voltammétrie cyclique. . . . .
Several molecular receptors of metallic cations, associating the tetrathiafulvalene unit to a chelating site have been synthesized. The design optimization, in relation to the basic systems concerns : the redox site (the choice of a bis-pyrrolo TTF skeleton avoids the Z/E isomerization problems met with the tetrathio TTF derivatives) ; the chelating unit (the preparation of macrocycles varying by their size (polyoxaethylene chains) or by their nature (polyether chain, diazacrown, dioxocyclam) should allow trapping of other cations. These syntheses have been carried our using high-pressure or high-dilution techniques. Complexation properties of these host molecules have been determined using different methods (mass spectrometry, NMR, UV-visible spectroscopy and cyclic voltammetry). Unprecedented properties in the TTF receptors family, for the complexation of Ba2+ and Pb2+, have been found. The switchable character of metal chelation, as a function of the applied electrochemical potential, has been demonstrated by cyclic voltammetry. . .

Abstract:
Cette étude concerne l'exploitation de l'électrodialyse dans le traitement d'effluents issus de l'industrie agro-alimentaire. Le fluide d'étude choisi est le lactosérum. La compréhension des interactions ioniques au cours de la déminéralisation de solutions synthétiques de composition ionique connue donne lieu à une étude expérimentale et une modélisation. Le modèle proposé permet de simuler des déminéralisations par électrodialyse à partir d'un calcul des mobilités apparentes dans la membrane des ions présents dans le milieu. Le modèle a egalement permis de mettre en évidence les interactions entre équilibre de complexation et élimination du calcium par électrodialyse dans le lactosérum. Les résultats sont exploités dans la mise en oeuvre d'un procédé de précipitation thermique de l'a-lactalbumine à son point isoélectrique en utilisant comme matière première un lactosérum démineralisé. Cela entraîne la valorisation d'une partie du lactosérum et contribue à son recyclage.

Abstract:
La complexation du calcium par des matieres humiques d'origines diverses (leonardite-tourbe-compost) a ete etudiee a differentes valeurs de ph par des techniques potentiometriques et conductimetriques en utilisant l'acide ethylene diamine tetracetique comme molecule de reference. Le pouvoir complexant augmente de ph5 a ph9. Il varie avec la nature des matieres humiques utilisees, elle-meme liee aux conditions d'extraction, a la matiere premiere de depart et a un eventuel traitement des matieres avant extraction. Les valeurs maximales sont obtenues pour les produits issus de leonardite. La complexation du calcium devrait permettre, en sol calcaire, d'ameliorer l'alimentation phosphatee des vegetaux en limitant la retrogradation des phosphates sous forme apatitique. Une culture de ray grass realisee en vases de vegetation montre que les solutions de matieres humiques extraites de tourbe et de compost entrainent une augmentation de l'exportation du phosphore (jusqu'a 210% d'augmentation). Par contre les solutions extraites de leonardite restent sans effet sur l'alimentation phosphatee. Il n'y a donc pas de relation directe entre pouvoir complexant vis-a-vis du calcium et amelioration de l'alimentation phosphatee. D'autres mecanismes interviennent donc pour expliquer l'effet des matieres humiques sur le developpement et l'alimentation minerale des vegetaux. Les solutions ne presentant pas d'effet sur l'alimentation phosphatee sont susceptibles d'agir sur l'alimentation azotee ou en oligoelements. Ainsi les produits issus de leonardite renferment de grandes quantites de fer, tres solidement fixe, qui pourra peut-etre etre disponible pour les vegetaux lors de la mineralisation des matieres humiques

Dans ce travail, nous avons etudie des calix 4 arenes. Ce sont des oligomeres cycliques formes de quatre unites phenoliques. Les etudes realisees jusqu'alors concernaient des composes possedant le meme substituant r en para de l'oh phenolique. Nous avons donc etendu l'etude a des composes comportant differents substituants en particulier pour apprecier la deformation de la symetrie du macrocycle. D'autre part, la cristallisation d'un calix 4 arene de formule symetrique a partir de differents solvants (xylenes et ethylbenzene) a donne des composes donnant des cliches de poudres differents. Notre travail a alors consiste a etudier les differentes conformations des calixarenes dans les complexes obtenus et leur evolution en fonction de la temperature. Les resultats principaux sont les suivants: a) symetrie 4 du macrocycle dans le complexe 1:1 avec le paraxylene; b) symetrie m du macrocycle dans le complexe 1:1 avec le metaxylene; c) symetrie 4 mais complexe 2:1 avec l'ethylbenzene. Les etudes par analyse enthalpique differentielle et par thermogravimetrie ont permis d'analyser l'evolution des complexes par pertes successives des molecules de solvants.

Abstract:
Les conditions de stabilisation d'un oxyde soluble sont caracterisees par le biais de techniques potentiometriques, de diffusion quasi-elastique de la lumiere (mobilites electrophoretiques, epaisseurs hydrodynamiques), et de comptage de particules. La fonction acrylique des polymeres (acide polyacrylique et polyacrylamides partiellement hydrolyses), forme un complexe tres stable avec les produits de dissolution de l'oxyde. Lorsque la concentration du polymere est initialement en defaut, voire en leger exces, par rapport a la concentration d'equilibre en ions aluminium dissous (en absence de polymere), l'adsorption s'apparente a une separation de phase, et conduit a des niveaux d'adsorption eleves. L'interface polymere, fortement complexee, est chargee positivement. Ces conditions, qui correspondent a une situation de forte agregation des suspensions, evoluent considerablement avec le temps. La lente fragmentation subsequente, qui peut etre decrite theoriquement a l'aide d'un processus de fragmentation collisionnel non lineaire, se traduit par une restauration, aux temps tres longs, de la distribution en taille initiale de l'echantillon. Lorsque le polymere est initialement en gros exces, le niveau d'adsorption et l'epaisseur de la couche sterique restent faibles, le polymere non adsorbe, faiblement complexe, induit une dissolution en continu de l'oxyde. Bien que la charge electrique de l'interface polymere soit globalement negative, une lente agregation est observee indiquant que ce systeme est metastable

Abstract:
Les flavonoïdes (polyphénols) sont une classe de molécules naturelles très répandues dans les plantes et dans l'alimentation et dotées d'une variété de propriétés biologiques et pharmacologiques. Les flavonoi͏̈des présentent, pour la plupart, un squelette de type2-phényl-1-benzopyrane diversement substitué par des groupements OH et OMe. Les différentes familles de flavonoi͏̈des se distinguent par la structure de l'hétérocycle oxygéné. Les groupes OH des flavonoi͏̈des sont souvent glycosylés voire sulfatés. En outre, les groupements glycosyles sont fréquemment acylés par des résidus d'acide organique (acide malonique et succinique, dérivés hydroxylés et/ou méthoxydés des acides benzoi͏̈que et cinnamique). Les groupements sulfates, glycosyles et acyles sont susceptibles de modifier les propriétés caractéristiques des flavonoïdes (propriétés antioxydantes et colorantes, complexation d'ions métalliques) ainsi que leur biodisponibilité, leur solubilité dans l'eau, leur affinité pour les protéines. . . Plusieurs méthodes simples et régiosélectives ont été mises au point afin de préparer, à partir de flavonoïdes commerciaux et peu coûteux (aglycones ou glycosides), des dérivés sulfatés (sulfatation de l'aglycone ou de la partie osidique) et des glycosides acylés par des résidus aromatiques ou aliphatiques. Les flavonoi͏̈des ainsi élaborés ont ensuite fait l'objet d'études conformationnelles par RMN et modélisation moléculaire ainsi que d'études de complexation (ions métalliques, albumine du sérum, pigments polyphénoliques) et de pouvoir antioxydant par spectroscopies UV-visible et de fluorescence qui montrent clairement l'influence des modifications chimiques sur les propriétés caractéristiques du noyau polyphénolique.

Abstract:
Ce travail s'inscrit dans le cadre d'un possible traitement des effluents de Très Faibles Activités (TFA). Parmi ces effluents, certains contiennent du 60Co qui est complexé à des composés organiques tels que l'acide éthylènediaminetétraacétique (EDTA) limitant alors les traitements existants par des méthodes conventionnelles. Ce travail de thèse porte sur l'évaluation de l'efficacité de Procédés d'Oxydation Avancée (UV/H2O2 et UV/TiO2) en vue de dégrader l'EDTA pour libérer le 60Co et ainsi le piéger (par précipitation et/ou adsorption sur des matrices minérales). En effet, l'étude d'adsorption a mis en évidence la capacité du TiO2 à adsorber le cobalt lorsqu'il n'est pas complexé. La précipitation totale du cobalt est quant à elle possible à pH 10 mais peut être réalisée dès pH 9 en présence d'irradiation UV-C. Le flux photonique émis par la lampe a été déterminé par actinométrie chimique et par la méthode de Keitz qui ont données des résultats similaires. L'efficacité des différents procédés pour dégrader l'EDTA et le complexe Co-EDTA a été étudiée en considérant l'influence de plusieurs paramètres (pH, mode d'agitation, type de catalyseur, concentration en H2O2...). Dans leurs conditions optimales, les procédés UV/TiO2 et UV/H2O2 permettent de dégrader et de minéraliser efficacement l'EDTA (composés azotés essentiellement minéralisés en ammonium). Après dégradation du complexe Co-EDTA, il est alors possible de récupérer la totalité du cobalt par adsorption sur le TiO2 et/ou par précipitation. Les procédés ont ensuite été appliqués à un effluent nucléaire contenant du 60Co complexés à des composés organiques. Les POA ont permis d'améliorer de manière significative les facteurs de décontamination en comparaison des méthodes de traitement conventionnelles
This work is part of a possible treatment of effluents of Very Low Level (VLL). Some of these effluents contain 60Co which is complexed with organic compounds such as ethylenediaminetetraacetic acid (EDTA), which limits existing treatments by conventional methods. This PhD work focuses on the evaluation of the efficiency of Advanced Oxidation Processes (UV / H2O2 and UV / TiO2) in order to degrade EDTA to release 60Co and thus trap it (by precipitation and / or adsorption on mineral matrices). Indeed, the adsorption study has demonstrated the ability of TiO2 to adsorb cobalt when it is not complexed. The total precipitation of cobalt is possible at pH 10 but can be performed at pH 9 in the presence of UV-C irradiation. The photon flux emitted by the lamp was determined by chemical actinometry and by the Keitz method which gave similar results. The effectiveness of the various processes to degrade EDTA and the Co-EDTA complex was studied by considering the influence of several parameters (pH, agitation mode, type of catalyst, H2O2 concentration, etc.). Under their optimal conditions, the UV / TiO2 and UV / H2O2 processes can effectively degrade and mineralize EDTA (nitrogen compounds that are essentially mineralized to ammonium). After degradation of the Co-EDTA complex, it is then possible to recover all the cobalt by adsorption on TiO2 and / or by precipitation. The processes were then applied to a nuclear effluent containing 60Co complexed with organic compounds. POAs have significantly improved decontamination factors compared to conventional treatment methods

Abstract:
As it is envisioned today, the first segment of the UREX+ process uses low nitric acid concentrations for U(VI) extraction where pertechnetate anion, TcO4−, can be co-extracted with the uranyl and nitrate into TBP-hydrocarbon solutions. A reductant complexant, acetohydroxamic acid (AHA) is added to the process through the scrub to limit the extractability of plutonium and neptunium. Recent work performed in our laboratory (Ref. 1) demonstrated that TcO4− undergoes reductive nitrosylation by AHA under a variety of conditions. The resulting divalent technetium is complexed by AHA to form the pseudo-octahedral trans-aquonitrosyl-(diacetohydroxamic)-technetium(II) complex ([Tc(II)(NO)(AHA)2H2O]+). In this paper, we are reporting the extraction of [Tc(II)(NO)(AHA)2H2O]+ complex by new designed macrocompounds as well as commercially available crown ethers from 18-crown-6 to 24-crown-8 in ring size and of varying derivatization. Several organic diluents with different dielectric constants are used to enhance the distribution coefficient of technetium (II). The experimental efforts are focused on determining the best extraction conditions by varying the macrocomponds nature and concentration, and the organic phase composition.

Abstract:
The decontamination factor of liquid waste containing 60Co is generally weak. This is due to the presence of complexant molecules. For instance, complexation of EDTA with 60Co decreases efficiency of radioactive waste treatment. The aim of this study was to degrade EDTA in H2O and CO2 and to concentrate free 60Co in order to increase decontamination factor. A first test of radioactive waste treatment by photocatalysis was allowed to increase decontamination factor (60Co) from 16 to 196 with a device requiring to be improved. The present work concerns the first step of the degradation process development with a more powerful device. These first experiments were leaded to follow the only EDTA oxidation. EDTA degradation was carried out by the following Advanced Oxidation Processes (AOP): UV/H2O2 (photochemistry); UV/TiO2 (photocatalysis); UV/TiO2/H2O2. A specific reactor was achieved for this study. The wavelength used was 254 nm (UVC). The photocatalytic degradation of EDTA was carried out with Degussa P-25 titanium dioxide (TiO2), which is a semiconductor photocatalyst. The degradation degree of EDTA and the intermediate products were monitored by TOC and ionic chromatography methods. The effects of various parameters such as pH and the quantity of H2O2 were studied. This allows us to conclude that basic pH slows down EDTA degradation. The study showed that UV/H2O2 process was the most effective treatment process under acid conditions. The rate of EDTA degradation was very high and reached 95% in 120 minutes. The presence of glyoxilic, oxalic, glycolic and formic acids was detected as degradation products. Among the intermediates produced by photochemistry, NO3− ions presence informed of the amine degradations. These results highlighted faster EDTA degradation by photochemistry than photocatalysis.
