Abstract

In order to research the feasibility of monitoring chromium contaminated field using complex dielectric constant method, we designed an experiment to compare the soil complex dielectric constants in conditions of different chromium pollution concentration, soil water content and void ratio. The result shows that, the complex dielectric constant of contaminated soil decreases obviously with the increasing frequency. And, when the frequency is lower than 50MHz, a significant change of the real and imaginary parts of soil complex dielectric constant can be observed. Moreover, with the increasing chromium pollutants concentration, water content and void ratio, both of the real and imaginary parts of soil complex dielectric constant increase as well. With the analysis of the relationship among soil dielectric constant, moisture content, and chromium pollution concentration, we built two soil dielectric constant models on the real quantity and imaginary quantity. Therefore, through the comparison of the real and imaginary quantity of the complex dielectric constant, we could evaluate and monitor the chrome pollutions.
