Повний текст джерелаThis work focuses on the synthesis and characterization of new nanostructured materials that can be potentially proposed as alternatives in the field of nuclear decontamination. The first part is devoted to the state of the art on the use of inorganic materials for decontamination purposes, with the emphasis placed on their sorption capacity and selectivity. The layer materials are considered as offering potential for such applications. In consequence, the main efforts in this work have been focused on manganate and vanadate nanostructures.Solvothermal synthesis of these materials was developed on the basis of micro-wave oven procedures to control the materials structuring, thus leading to vanadate nanotubes and manganate nanoflowers. The optimization of vanadates was carried out by taking into account the effect of various factors (e.g., duration of maturation and heating stages, nature and mass of the template) on both the structural and textural properties of the resulting substrates. It was demonstrated that the scrolling of the layers was strongly influenced by the amount of amine and its chemical structure. Indeed, only the amine templates possessing long chains allowed homogeneous nanotubes to be achieved. More information about the structuring process was inferred when coupling experimental and simulation approaches.The sorption performance of the resulting solid materials in terms of sorption capacity and selectivity was assessed in model and simulated systems obtained by using either ultrapure or river water with an adequate composition as solvent to prepare aqueous solutions of strontium or/and cesium. The results of sorption experiments clearly indicated strong selectivity of the vanadate structures toward Cs+ and that of the manganate ones toward Sr2+, even under conditions of competition among various ionic species.Direct calorimetry measurements of heat effects accompanying sorption were correlated with the results of molecular simulation studies to shed more light on the origin of the improved sorption selectivity

Повний текст джерелаThe objective of this thesis is to study the ionics decontamination of aqueous solutions by ionic oxide exchangers with a particular focus on the strontium adsorption by the sodium nonatitanate. The goal is to develop a predictive model takes into account the phenomena involved, and the deviations to the ideality into the solution but also in the material.The activity coefficients of the ions in solution have been calculated from an approach based on the MSA theory (Mean Spherical Approximation), where the specific association phenomenons have been taken into account. This allowed for calculating the ionic activity coefficients in the ternary mixtures. The validity of mixture laws of Zdanovskii-Stokes-Robinson and McKay-Perring has been also specified. Two activity models, which represent the long and the short-range interactions, have been used for the ionic studied in the solid. The adsorption isotherms at various concentrations have been hence modeled.A pH-metric study has also been performed on the sodium nonatitanate in order to determine the hydrolysis constant as well as the solid hydrolysis rate. A structural and morphologic study allowed for highlighting that for highly acidic solutions the sodium nonatitanate is dissolved and precipitated again under different crystallographic forms of the TiO2

Повний текст джерелаStrontium titanate is an extensively studied material with a wide range of application, for instance in photo-catalysis and most importantly, it is used as a substrate in growth of functional oxides. The surface chemistry is crucial and hence understanding the surface structure on atomic scale is essential for gaining insight into the fundamental processes in the aforementioned applications. Moreover, there exist a lot of evidence that this surface chemistry might be controlled to considerably by extrinsic species, such as residual hydrogen and water. Investigating the properties of water and oxygen on the strontium titanate surface is certainly a natural starting point for a theoretical study based on density functional theory, because these species are practically present on the surface on a wide range of experimental conditions and they are computationally feasible. For the oxygen and water adsorption the binding energy is controlled by long-range surface relaxations leading to an effective repulsion of the adsorbed specimen. The isolated oxygen ad-atom forms a covalently bonded “quasi-peroxide anion” in combination with a lattice oxygen atom. Contrariwise, in all investigated configurations containing water molecules and hydroxyl groups, the respective oxygen atoms assumed positions close to the oxygen sites of the continued perovskite lattice of the substrate. Most remarkably, on the strontium oxide termination, the water molecules adsorbs and dissociates effortlessly leading to the formation of a pair of hydroxyl groups. For the titanium dioxide termination, a coverage dependent adsorption mode is observed. Densely packings stabilize water molecules, whereas at lower coverage and finite temperatures the formation of hydroxyl groups is found. The energetics responsible for this behavior is consistent with recent experiments by Iwahori and coworkers.
Limousin, Guillaume. "Transfert de solutés réactifs dans la zone non-saturée des sols à différentes échelles d'observation." Phd thesis, Université Joseph Fourier (Grenoble), 2006. http://tel.archives-ouvertes.fr/tel-00128889.
Повний текст джерелаLe site de la centrale nucléaire de Brennilis (Finistère) a été choisi pour étudier le transfert du strontium, du cobalt et de traceurs inertes dans le sol. Plusieurs échelles d'observation ont été testées (tube à essai, réacteur agité à flux ouvert, colonne de sol tamisé, lysimètre de sol remanié ou non, mesures de terrain) afin de déterminer, à chaque échelle, les principaux facteurs d'influence du transfert des contaminants, puis de vérifier l'adéquation des différentes échelles d'observation entre elles et leur représentativité par rapport au terrain.
Concernant les propriétés hydrodynamiques du sol, la porosité, la teneur en eau sur le terrain, la vitesse porale aux teneurs en eau du terrain, la conductivité hydraulique à saturation et le coefficient de dispersion de ce sol remblayé sont spatialement moins hétérogènes que dans les sols agricoles ou non-anthropisés. Les résultats obtenus en lysimètre et sur le terrain suggèrent que l'hydrodynamique de ce sol non-structuré peut être étudiée sur un prélèvement remanié si le volume de sol est grand par rapport aux rares cailloux de grande taille.
Concernant les interactions chimiques sol-contaminants, les isothermes du cobalt et du strontium sont non-linéaires au-delà de 10-4 mol.L-1. L'adsorption et la désorption du cobalt sont rapides et indépendantes du pH. Au contraire, en deça de 3,5.10-6 mol.L-1, les isothermes du cobalt et du strontium sont linéaires, la désorption du cobalt est nettement plus lente que l'adsorption et le coefficient de partage ainsi que les cinétiques sont nettement dépendants du pH. Pour les deux éléments, les résultats obtenus en tube à essai, en réacteur agité à flux ouvert et en colonne de sol tamisé sont concordants. Par contre, l'adsorption du strontium en tube à essai à l'équilibre n'explique pas totalement les résultats du traçage sur le terrain.

Повний текст джерелаThis PhD thesis examined the mechanisms of storage and release, from and elementary and isotopically point of view, of calcium (Ca) and strontium (Sr) onto or into mineral phases commonly encountered within soils (primary minerals, clay minerals, oxy-hydroxides, pedogenic carbonate). A robust δ88Sr measurements method had to be developed in the laboratory and validated by the measurement of international reference materials, mostly never measured in the literature. The results of this work show that Ca adsorption onto phyllosilicate minerals generates a quantifiable isotopic fractionation by preferential uptake of the light isotope (40Ca) under our experimental conditions when the minerals have a significant structural charge and specific surface area and/or an interlayer space open to hydrated cations adsorption. A study on rhizoliths in natural environment has also highlighted that the combination of Ca and Sr isotopes allows an effective tracing of sources and mechanisms in the problematic related to the storage of these two elements within soils

Повний текст джерелаHydraulic fracturing generates wastewater ranging from 2 to 8.5 million gallons per well. Suspended solids, total dissolved solids, hydrocarbons, organic compounds, and heavy metals are some of the common contaminants present in the fracking wastewater. In this work, pecan shell-based activated carbon (PSBAC) was prepared, characterized, and applied for the removal of Ba (II), Fe (II), and Sr (II) from synthetic fracking wastewater. The PSBAC had a high specific surface area of 1516 m2/g and pore volume of 0.8 cm3/g. The effects of initial adsorbate concentration, adsorbent dose, and temperature were investigated, and an optimum condition for the present adsorption system was identified. Results showed that the Langmuir model best fit the adsorption systems with the PSBAC having maximum adsorptive capacity of 3.33 mg/g for Ba (II), 41.66 mg/g for Fe (II), and 8.8 mg/g for Sr (II). Kinetic studies revealed that sorption of the metals was not limited by intra-particle diffusion. The pseudo-second order kinetic model had the best fit, indicating chemisoprtion is the rate limiting step. The adsorption process was thermodynamically favorable and endothermic in nature.
