Abstract: | Analytic expressions for dielectric permittivity factor ε1(ω) and dielectric dissipation factor ε2(ω) of electrolyte solutions are obtained, based on the ratio between complex factors of dielectric permittivity and specific conductivity. The range of frequency dispersion of dynamic factors ε1(ω) and ε2(ω) for aqueous solutions of LiCl, NaCl, KCl, and CsCl is considered. Numerical calculations are performed for friction coefficients β a and β b ; relaxation times τ a , τ b , and τ ab ; and factors ε1(ω) and ε2(ω) in a wide range of variation for ρ; concentration c; temperature T; and frequencies ω. The resulting theoretically calculated ε1(ω) and ε2(ω) values and the Cole–Cole diagram are in quantitative agreement with experimental data. |
