Quantitative Parameters

Comparatively large amount of works has been devoted to the investigation of the nearest environment of cesium ions in aqueous solutions. But up to date there are no precise quantitative parameters of it. Information about influence of concentration on cesium salts solutions structure is also absent. In order to get the coordination number of Cs+ ion and its dependence on the amount of dissolved salt the set of aqueous solutions of cesium iodide have been studied by X-ray diffraction method in wide concentration range under ambient conditions. Radial distribution functions (RDFs) of the solutions investigated have been calculated from experimental intensity curves of X-ray scattering. Interpretation of experimental peaks on RDFs has been made. On the basis of experimental results and literature information some physically reasonable models of solution have been constructed. Theoretical RDFs have been calculated for every model. Then an optimization procedure has also been made. On the ground of the best fitness between experimental and theoretical RDFs the optimal models for every solution have been found. All quantitative parameters have been tabulated and analyzed. Hydration numbers of Cs+ and I- increase with dilution, reaching in the solution of molar ratio 1:80 values 6.3 and 4.1, respectively. Interparticle distances of Cs+–ОН2 and I- –ОН2 are equal approximately to 0.312 and 0.359 nm. The ions do not form the second coordination shells. It has been determined that contact ion pairs Cs+–I- exist in whole concentration range investigated.Forcitation:Smirnov P.R., Grechin O.V., Voevodina E.A.
