Research Progress on Leaching and Adsorption Technology for Polycyclic Aromatic Hydrocarbons

摘要: 梳理当前淋洗技术对去除土壤中多环芳烃的研究现状，旨在为淋洗技术去除土壤中多环芳烃污染的相关研究提供参考和借鉴。分别阐述了不同淋洗剂、淋洗机制以及影响淋洗的因素，其中分别从淋洗剂的种类和淋洗的机制及动力学对土壤在多环芳烃的去除效果和去除机制分析两个层面研究淋洗剂对多环芳烃的去除性能。并对淋洗后的处理进行分析，这为今后开展淋洗技术对去除土壤中多环芳烃的研究提供参考和借鉴。

Abstract: The current research status of leaching technology for the removal of polycyclic aromatic hydro-carbons (PAHs) in soil is summarized in order to provide reference and guidance for relevant studies on the remediation of PAH-contaminated soil using leaching technology. Different leaching agents, leaching mechanisms, and factors influencing leaching are discussed. Specifically, the types of leaching agents and the mechanisms and kinetics of leaching are analyzed from two perspectives to understand their effectiveness in removing PAHs from soil. Additionally, post-leaching treatment is also analyzed. This provides a reference and guidance for future research on the application of leaching technology for the removal of PAHs in soil.
