重金属汞污染砂的交流电阻抗特性研究

Study on AC impedance characteristics of sand polluted by heavy metal Hg

以重金属汞污染砂为研究对象,对不同汞含量、不同含水量的汞污染砂在不同电流频率下的交流电阻抗进行了测试分析,研究结果表明:不同汞含量污染砂的交流电阻抗均随着电流频率和含水量的增加而减小,二者之间呈现了相关性较好的幂函数关系;随着汞含量的增加,交流电阻抗减小很明显。

Taking heavy metal Hg contaminated sand as the research object,AC impedance under different current frequency of sand in different Hg content and water content was tested,the results show that： the AC impedance decrease with the increase of both current frequency and water content,good power function relationships were got,the AC impedance decrease with the increase of Hg content.
