Analysis of Dielectric Properties and Influencing Factors of Zn Contaminated Soil
Studying on the influence of heavy mental contents and moisture contents on dielectric properties of soil and its internal mechanism, which is the basis of quantitative detection of soil pollution by ground penetrating radar (GPR). Taking zinc contaminated soils as an example, soil cakes are made by adding zinc salt solution of different mass concentration into silty clay. Then, the complex permittivity of soils in different wet densities, different moisture contents were measured by vector network analyzer. The laws of variation of complex permittivity were summarized and grey relational analysis was carried out. Finally, the mechanism of influence of various factors on dielectric properties of zinc contaminated soil was explained by dielectric theory. The results show that the real part of complex permittivity of zinc contaminated soil is most affected by moisture content, which increased with the increase of moisture content, the correlation between real part and moisture content was 0.93. The imaginary part of complex permittivity is most affected by zinc salt content, which increased with the increase of zinc salt content, the correlation between imaginary part and zinc salt content was 0.77.
