电动力学修复铜污染土壤的研究

Research on Electrodynamics Remediation of Copper Contaminated Soil

采用电动力学方法修复重金属污染土壤。研究中采用高岭土模拟铜污染土壤,电化学装置的电压强度为0.5 V/cm,通过在阴阳极室加入不同的缓冲液来确定铜的迁移效果。结果表明在阴极室加入乙酸作为缓冲液可以有效提高铜的迁移效果,在阳极加入柠檬酸能够有效的与铜形成络合物达到更好的迁移效果。

Electrodynamics remediation method was applied to the heavy metal contaminated soil. Kaolin simulation was used as copper contaminated soil. The voltage strength of electrochemical device was 0.5 V/cm. The migration effect of copper was determined by adding different buffers into the anodic-cathodic chamber. The results showed that the migration effect of copper could be improved by adding acetic acid in the cathodic chamber as buffer, while citric acid adding in the anodic chamber could effectively form a complex with copper to achieve better migration effect.
