Full textThe electrokinetic coefficient is simulated in a large range of salinities using the Lattice Boltzmann method in a 2-D channel. The effect of permittivity and viscosity is discussed. The validity of the Helmholtz Smoluchowski equation using strong zeta potentials is assessed. A model of bulk fluid conductivity is derived, taking into account the local variations of conductivity which have a significant impact in the presence of polyvalent counterions. Extended to unsaturated conditions, the model shows that the electrical charge density associated to the air-water interface is a key component. The coefficient shows a non monotonous behaviour, with an enhancement compared to the saturated state. The magnitude of this enhancement depends on the dynamic state of the bubbles, moving or entrapped. The multiphase transport aspect is associated to a numerical study of the influence of the sample geometry on the measurement of the capillary pressure / saturation relationships used in hydrology

Full textThis work takes its place in the application of «Green Chemistry» in Separation Sciences. Indeed, the Ionic liquids represent a new generation in the family of green solvents with their unique physicochemical properties and they appear particularly well adapted to the electrokinetic techniques. Thus, we intended to test the potentialities of original Ionic Liquids based on phenylcholine and ethylcholine respectively, as new mediums in this context by Capillary Electrophoresis. Two sets of themes were envisaged: the first was related to the analysis of alkaline and alkaline-earth cations by Capillary Electrophoresis, with indirect UV detection, the Ionic Liquid played simultaneously the role of the running electrolyte and the chromophore, generating the background signal. While the second was referred to the study of the enantioseparations of original binaphthols atropisomers, in Capillary Electrophoresis by means of cyclodextrins (CD-CZE), in presence or not of chiral ionic liquids

Full textThe works presented in this thesis focuse on the contribution to the study of electrokinetic processes applied to the dredged sediments. Two aspects have been studied ; the first one deals with the preprocessing phase and develops the dewatering process, while the second aspect is devoted toe electroremediation. Dewatering dredged sediments by electrokinetics appears as a promising technique. In this framework, tests were performed under various conditions to provide a general understanding of the behaviour of the sediment subjected to a single electric field or combined with a mechanical stresses, and also to assess the performance of the dehydratation with particular emphasis on the determination of physicochemical parameters. Subsequently, studies were conducted to assess the potential of the Electrokinetic process on a dredged-contaminated sediment using additives with well-defined chemical properties. In order to target the two types of organic and inorganic contaminants, it was interesting to combine the advantages of several types of additives. For example, combining an acid with a surfactant can improve the electroremediation process. The improvement of this process can also be carried regarding to the economic aspect through two parameters; energy consumption with the periodic voltage treatment and the concentration of the additive. Therefore this electroremediation technique combines the advantage of being more competitive and efficient for several elements (organic and inorganic) present in the solid matrix

Full textIn confined structures, such as mesoporous silica, the mobility of the cations and the surface/cations interactions are key phenomena. They drive adsorption properties, which control numerous applications, especially for extraction and separation. This modelling work describes equilibrium and transport interface properties that control ion exchange and ionic adsorption. The physical and chemical properties of adsorption processes of alkali cations at the surface of charged silica is studied thanks to a multiscale approach based on a molecular description. The systematic study of alkali serie (Li+, Na+, K+ and Cs+) has been studied to that goal. The theoretical framework is Mc Millan-Mayer theory. The latter, which is known to be of fundamental significance for bulk solutions is found to be also relevant for confined media. The mean force potential of Mc Millan-Mayer between ions and surface sites has been calculated by Umbrella Sampling associated to the WHAM algorithm. The most important phenomenon we identified corresponds to the existence of Contact Ion Pairs (CIP) between the surface oxygen and the cations, without separating solvent molecules. The CIP correspond to the first minima in the potential curves if the associated energy is more than the thermal agitation (kT). For small ions (lithium) this surface complex is especially stable, adsorption constant and residence time being particularly high so that the direct molecular simulations are very difficult. A selectivity inversion has been observed between silanolates and siloxanes. Adsorption is different for kosmotropic ions (as Li+) which has to be dehydrated to be adsorbed and chaotropic ions (as Cs+) for which the solvent bound is weaker. Adsorption constants for sites of the same nature are not equal. The study of the electrokinetic phenomena (electro-osmosis and surface conductivity) has also been performed by comparing the classical descriptions (Poisson-Boltzmann, Smoluchowski, and Bikerman models) to molecular simulations. The traditional picture of the interface with several layers (inner and outer Helmholtz, Stern and Gouy-Chapman layers, shear plane) is found to be replaced by a simpler but more efficient model. For the ions, two domains are obtained: (i) CIPs, firmly bound to the surface that transmit the electrical force to the solid (and not the fluid) (ii) other ions that are globally free that transmit the electric force to the fluid. No space dependent viscosity or dielectric constant have been obtained. On the other hand, a decrease of ion mobility in the vicinity of the surface has been observed. This phenomenon can be quantitatively understood as a hydrodynamic effect that comes from the solid surface, which hinders the backflow of the solvent. This work allows a better characterization of charged glass-solution interfaces for separation science. It shows how molecular simulations can not only predict the parameters of macroscopic models (adsorption constant, transport coefficients), but also modify the latters in order to make them in agreement with molecular descriptions. Such a strategy can be extended to more complex systems, such as models of grafted surfaces
