Abstract The complex resistivity dispersion experiment on soils with different water and chromic salt proportions constitutes the basis of the complex resistivity detection method used to evaluate the field polluted by chromium residue. Based on experiments on the soil complex resistivity dispersion properties under various kinds of conditions, the authors have found that the complex resistivity amplitude, phase, in-phase resistivity and out-phase resistivity can be influenced by the water content and contamination content, but the complex phase and out-phase resistivity and the phase angle have obvious dispersion properties. The experiment results show that the complex resistivity detection technology based on soil dispersion properties can be used to evaluate the field polluted by chromium residue rapidly and effectively.
