title: Effect of ionic environment on the transport of cesium ion in alkali chloride solutions from radio tracer studies.
abstract: The rate of transport (diffusion) of cesium ion in aqueous solutions of all the alkali metal chlorides together with cesium iodide and cesium fluoride (generalized name MX) at 25 degrees C temperature has been measured by the radioactive tracer technique using (134)Cs as tracer, over the 0.0<concentration>4.0 M. These diffusion data along with other transport data in the literature are used to calculate the velocity correlation coefficients (VCC) for Cs-M, Cs-H(2)O and Cs-X, which actually represent the ensemble average time integrals of the velocity correlation functions of the referred pair of species. The concentration dependence of VCC gives a quantitative estimate of the influence of environment and its dynamics on the transport of cation cesium in a highly correlated system like aqueous solutions of 1-1 electrolytes.
