摘　　要：全氟辛酸(PFOA)和全氟辛烷磺酸(PFOS)是工业生产中使用最广泛的全氟烷基化合物。由于PFOA和PFOS的难降解性以及远距离迁移性,其在全球范围内被广泛检出。该文讨论和总结了PFOA和PFOS在土壤和地下水中的危害和修复研究进展。研究表明,各种物理和化学因素显著影响PFOA和PFOS在环境中的迁移。在对活性炭吸附技术、膜过滤技术、光催化高级氧化技术、电化学和电絮凝技术、新型材料吸附技术、生物降解技术以及其他新型修复技术性能讨论中发现光催化高级氧化技术具有最佳的去除PFOA和PFOS效果;材料改性构建的新型吸附材料也可以实现很高的去除效率。该综述系统归纳和总结各种修复技术对PFOA和PFOS的去除效果和机制,可对进一步研发和优化PFOA和PFOS的修复技术提供系统性的参考依据。Perfluorooctanoic acid(PFOA)and perfluorooctane sulfonic acid(PFOS)are the most widely used perfluoroalkyl substances(PFASs)in industrial production.Due to recalcitrance and long-distance mobility of PFOA and PFOS,they are widely detected around the world.The paper discussed and summarized the research progress of PFOA and PFOS hazard and remediation in soil and groundwater.Studies have shown that various physical and chemical factors significantly affect the transport of PFOA and PFOS in the environment.The performance of activated carbon adsorption technology,membrane filtration technology,photocatalytic advanced oxidation technology,electrochemistry and electro flocculation technology,new material adsorption technology,biodegradation technology and other new remediation technologies were discussed.It was found that photocatalytic advanced oxidation technology has the best effect for removing PFOA and PFOS.The new adsorption material could also achieve very high removal efficiency.This review systematically generalized and summarized the removal effects and mechanisms of various remediation technologies for PFOA and PFOS remediation,which would provide a systematic reference for further developing and optimizing the PFOA and PFOS remediation technologies.
