| Abstract: |
| Heavy metals in soil have a very long incubation period, high biological toxicity, long-term impact on soil environmental quality and human living environment, and gradually attract widespread attention due to their characteristics of gradual accumulation in the food chain. Soil chemical elution technology is widely used in various fields of soil heavy metal remediation due to its high leaching efficiency and complete remediation. The research on this kind of technology starts relatively late in China, and research on principle of soil heavy metal remediation and leaching agent is not in-depth. Therefore, this paper makes a comprehensive analysis of leaching effects, advantages and disadvantages of different kinds of chemical leaching agents, aiming to provide a reference for prevention and control of soil heavy metal pollution. |
