Frequency Dispersion of Dielectric Permittivity and Dielectric Losses in Aqueous KCl and CsCl Solutions Depending on Their State Parameters

Section: Soft matter
Original Author's Text: Russian

Abstract: The frequency spectra of the coefficients of dielectric permittivity, ε1(ω), and dielectric losses, ε2(ω), ave been studied for aqueous KCl and CsCl solutions in wide intervals of the density ρ, concentration C, and temperature T. The research is carried out on the basis of the analytical expressions obtained for those parameters, by using the method of kinetic equations. Numerical calculations of ε1(ω) and ε2(ω), at various ρ, C and T are carried out with a certain choice of the solution model, the potential interaction energy Φab(|r|), and the radial distribution function gab(|r|) for ions of sorts a and b in the solutions concerned. The obtained results are in satisfactory quantitative agreement with experimental data.

Key words: dielectric permittivity coefficient, coefficient of dielectric losses, potential of intermolecular interaction, radial distribution function, fluid friction coefficient, relaxation times.
