摘要
疏水性有机污染物(Hydrophobic organic contaminants,HOCs)在土壤环境中分布广泛.由于不易从土壤颗粒中解吸,迁移性和生物有效性低,化学、生物与物理修复技术对土壤中HOCs的修复效果常受到抑制.表面活性剂对HOCs具有增溶能力,常被用于强化其他修复技术的处理效率.本文对近20年来表面活性剂在强化土壤化学、生物或物理技术修复土壤HOCs污染领域的研究与应用情况进行了分类总结,并比较分析了各类表面活性剂强化技术的适用性及局限性,提出了联合修复技术和表面活性剂泡沫是表面活性剂强化土壤HOCs修复的未来研究方向.
Abstract
Hydrophobic organic contaminant(HOCs)are widely distributed in soil environments.Due to their limited desorption from soil particles,low mobility and bioavailability,the effectiveness of chemical,biological,and physical remediation techniques on HOCs in soil is often inhibited.Surfactants,known for their solubilization capacity for HOCs,have been employed to enhance the efficiency of other remediation technologies.This review categorizes and summarizes research and applications of surfactant-enhanced techniques in remediating soil HOCs pollution over the past two decades.A comparative analysis of various surfactant-enhanced techniques is presented,highlighting their applicability and limitations.Furthermore,the potential of combined remediation approaches and surfactant foam technology is explored as promising avenues for future research in enhancing soil HOCs remediation with surfactants.
