Abstract:
The forms of occurrence of vanadium metal are determined by the major chemical reactions in the aquatic environment such as hydrolysis, oxidation, reduction, and precipitation. Depending on pH, potential and total concentration of inorganic ions and organic ligands, vanadium compounds may undergo various transformations to produce a whole range of chemical forms in aqueous systems. In this paper, a novel approach has been applied for calculating potential-pH (Pourbaix) diagrams, based on the developed thermodynamic analysis of chemical equilibria in the V–H2O system. On the basis of currently revised thermodynamic data for V(III), V(IV) and V(V) hydrolysis and original thermodynamic and graphical approach used, the repartition of their soluble and insoluble chemical species has been investigated. By means of ΔG–pH diagrams, the areas of thermodynamic stability of V(IV) and V(V) hydroxides have been established for a number of analytical concentrations of vanadium in heterogeneous mixtures. The obtained results, based on the thermodynamic analysis and graphic design of calculated data, are in good agreement with available experimental data.

Abstract:
L'astate (At, Z = 85) est un élément halogène rare, tous ses isotopes étant radioactifs. En raison des quantités disponibles limitées, aucun outil spectroscopique n'est applicable pour identifier la nature moléculaire des espèces d'At. En conséquence, la chimie de l'At reste méconnue. L'un de ses isotopes, ²¹¹At, est un candidat potentiel pour le traitement de cancers par thérapie alpha ciblée. Cependant, la connaissance limitée de ses propriétés chimiques a entravé les tentatives de marquage de ²¹¹At avec des molécules porteuses ciblant la maladie. Cela a conduit au développement d’un programme de recherches sur la chimie de base de At. Cette thèse s’intéresse plus particulièrement au diagramme de Pourbaix de l’astate et à la caractérisation de liaisons halogènes avec l’espèce AtI, au moyen de divers outils expérimentaux (chromatographie ionique, méthode de compétition et électromobilité). Dans une première partie, des études de spéciation de At en milieu alcalin confirment la présence de l'espèce At⁻ en conditions réductrices. Lorsque le potentiel augmente, l’espèce AtO(OH)₂⁻ se forme. Le changement de spéciation entre ces deux espèces est décrit pour la première fois. Dans une deuxième partie, la formation de liaisons halogènes entre l'espèce AtI et divers composés organiques a été étudiée. La réactivité se résume par une échelle de basicité nouvellement établie dont la force entre le donneur (AtI) et l’atome accepteur varie suivant l’ordre C ≤ O ≤ S (≈ Se)
Astatine (At, Z = 85) is a scarce halogen element, all of its isotopes being radioactive. Due to the limited available quantities, no spectroscopic tool is applicable to identify the molecular nature of At species. Consequently, the chemistry of At remains poorly known. One of its isotopes, ²¹¹At, is a potential candidate for the treatment of cancers by targeted alpha therapy. However, the limited knowledge of its chemical properties has hindered attempts to label ²¹¹At with disease targeting carrier molecules. This led to the development of a research program on the basic chemistry of At. This thesis focuses more particularly on the Pourbaix diagram of astatine and the characterization of halogen bonds with the AtI species, by means of various experimental tools (ion chromatography, competition method and electromobility). In the first part, speciation studies of At in alkaline medium confirm the presence of the At⁻ species under reducing conditions. As the potential increases, the AtO(OH)₂⁻ species is formed. The speciation change between these two species is described for the first time. In a second part, the formation of halogen bonds between the AtI species and various organic compounds was studied. The reactivity is summarized by a newly established basicity scale, with the strength between the donor (AtI) and the acceptor atom following the order of C≤ O ≤ S (≈ Se)

Abstract:
Motor car exhaust catalysts are some of the most important users of platinum, and much attention is given to the recycling of scrap platinum from spent exhaust systems. The dissolution of platinum from waste exhausts was previously only possible by pyrometallurgical processes or by the use of aggressive chemicals, such as aqua regia and cyanide, all of which, however, cause pollution problems. Recently the potential for the development of hydrometallurgical processes was identified. These processes are more efficient and more environmentally friendly than traditional processes. It was the aim of this study to investigate the oxidation of platinum with ozone as oxidizing agent in the presence of chloride as complexing agent. The influence of various factors, such as chloride ion concentration, pH and temperature were studied thermodynamically and electrochemically in order to achieve efficient leaching. The thermodynamic investigation, leading to the construction of Pourbaix diagrams of platinum in the presence of chloride, confirmed the possibility of the formation of stable aqueous complexes, as well as platinum oxides. From the electrochemical results obtained it can be concluded that ozone may be useful as an oxidizing agent, but according to the leaching results obtained, ozone holds few benefits compared to aqua regia and cyanide, although they still present some environmental challenges. The relatively low percentages of recovery obtained with leaching may be attributed to the rapid decomposition of ozone, which is affected by several factors, such as temperature, pH, initial concentration of ozone, ionic strength and stirring rate. Further optimisation of these factors can possibly prove ozone to be a useful oxidizing agent for the recovery of platinum.

Abstract:
L'alpha-radiothérapie est une technique particulièrement innovante de thérapie des cancers, tout en étant complémentaire des thérapies déjà existantes. Elle repose sur l'utilisation d'un vecteur spécifique (anticorps ou peptide) de la cellule cible à détruire, radiomarqué par un élément radioactif émetteur alpha. L'astate 211 est un candidat particulièrement intéressant compte tenu de l'énergie des particules α qu'il émet et de sa période physique (7,2 h). L'une des voies de marquage envisagée est l'utilisation de l'astate à un degré d'oxydation supérieur à zéro en tant que cation. En effet, l'astate est supposé présenter un caractère plus métallique que les autres halogènes du fait de son positionnement dans le tableau périodique. Cette voie de marquage a été peu abordée dans la littérature en raison du manque de données sur la chimie de l'astate aux degrés d'oxydation supérieurs à zéro. Le but de ce travail était donc d'explorer cette propriété de l'astate via la construction du diagramme Eh, pH (ou diagramme de Pourbaix) en milieu aqueux non complexant. Pour ce faire, ce travail s'est appuyé sur une double approche expérimentale / théorique. L'approche expérimentale utilise des méthodes dites de compétition pour identifier les espèces formées et les constantes thermodynamiques des équilibres étudiés. L'approche théorique utilise des méthodes de chimie computationnelle et fournie des informations à l'échelle moléculaire sur les systèmes étudiés afin de prédire les données thermodynamiques qui servent de support et complément à l'approche expérimentale. Un résultat important de ce travail montre la présence de deux espèces cationiques stables de l'astate en solution aqueuse, At+ et AtO+.

Abstract:
Two series of new mononuclear ruthenium complexes with hydrophobic or hydrophilic ligands [Ru(bda)L2] and [Ru(pdc)L3] (H2bda = 2,2'-bipyridine-6,6'-dicarboxylic acid; H2pdc = 2,6-pyridinedicarboxylic acid; L = pyridyl ligands) were synthesized and their electrochemical properties and catalytic activity toward water oxidation were examined. It was revealed that the hydrophobic ligands introduced to [Ru(bda)L2 ] improved the catalytic performance, ahnost twofold TON and TOF values were achieved compared to the [Ru(bda)] catalyst with hydrophilic ligands. The cyclic voltammogram of [Ru(bda)L2] exhibited marginal difference between the catalysts with hydrophobic ligands and hydrophilic ones, implying that the hydrophobic ligands promoted the catalytic activity by :lacilitating formation of a reaction intermediate dimer.

Full text
Abstract:
Total lead release in drinking water in the presence of free chlorine and chloramine residuals was investigated in field, laboratory and fundamental investigations for finished waters produced from ground (GW), surface (SW), saline (RO) and blended (B) sources. Field investigations found more total lead was released in the presence of chloramines than in the presence of free chlorine for RO and blended finished waters; however, there were no statistical differences in total lead release to finished GW and SW. Laboratory measurements of finished waters oxidation-reduction potential (ORP) were equivalent by source and were not affected by the addition of more than 100 mg/L of sulfates or chlorides, but were significantly higher in the presence of free chlorine relative to chloramines. Development of Pourbaix diagrams revealed the PbO2 was the controlling solid phase at the higher ORP in the presence of free chlorine and Pb3(CO3)2(OH)2(s) (hydrocerussite) was the controlling solid phase in the presence of chloramines at the lower ORP, which mechanistically accounted for the observed release of total lead as PbO2 is much less soluble than hydrocerussite. The lack of differences in total lead release to finished GW and SW was attributed to differences in water quality and intermittent behavior of particulate release from controlling solid films.
