摘要
本研究旨在探究污染土壤中重金属铅的螯合修复效果,采用EDTA作为螯合剂,通过不同浓度的螯合剂对污染土壤进行处理。实验结果表明,螯合剂浓度和处理时间对土壤中的铅浓度有显著影响。本文详细描述了实验设计、操作步骤和数据分析过程,并对修复效果进行评估。通过对比不同浓度螯合剂的实验数据,提出了一种可行的土壤重金属修复方法,并讨论了实验中pH值变化的影响,这项研究对于理解土壤环境污染的化学修复机制具有重要意义并可作为实际应用的参考。
This study aims to investigate the chelation remediation effect of heavy metal lead in polluted soil.EDTA was used as a chelating agent to treat polluted soil with different concentrations of chelating agents.The experimental results showed that the concentration of chelating agents and treatment time had a significant impact on the lead concentration in soil.The experimental design,operational steps,data analysis,and evaluation of remediation effects were described in detail.A feasible soil heavy metal remediation method was proposed by comparing experimental data of different concentrations of chelating agents,and the impact of pH changes in the experiment was discussed.This study is of great significance for understanding the chemical remediation mechanism of soil environmental pollution and providing reference for practical applications.
