Analysis on Dielectric Properties of Chemical Solution with Potassium Ion Under Different Concentrations

Abstract

The dielectric properties of electrolyte solution with K⁺ are studied. In this paper, the changes of complex permittivity of the potassium nitrate and potassium acetate with different concentrations are measured using coaxial line probe. It is shown that the changes of real part of the complex permittivity are all small and the changes of imaginary part of the complex permittivity of electrolyte solution are quite obvious. By analyzing the systems and variation error with different concentrations, a conclusion is drawn that there is an agreement for reference and measurement results which is important for environmental monitoring, remote sensing detection and imaging.
