摘要
全氟辛酸(PFOA)和全氟辛烷磺酸(PFOS)广泛应用于各种工业和家居产品的生产和使用中,因其具有热稳定性、化学稳定性和环境持久性等特殊性质,已在世界范围内广泛检出。目前,对于PFOA和PFOS在环境介质中的行为研究已有一些进展,本研究归纳总结了PFOA和PFOS在环境介质中的迁移行为和相关数学模型的研究进展。具体针对影响PFOA和PFOS在环境介质中迁移的机制(静电相互作用、疏水作用、配体交换和氢键)和因素(有机质含量、矿物类型、矿物含量、介质含水率、离子类型、离子强度和pH)以及可用于模拟的数学模型(对流-弥散模型、非平衡两点吸附模型、非平衡两区吸附模型、多速率模型、多过程限速传质模型,TOSD迁移模型)进行探讨和总结,以为后续更深入的科学研究提供综合性参考依据。
Perfluorooctanoic acid(PFOA)and perfluorooctanosulfonic acid(PFOS)are widely used in the production and application of a variety of industrial and household products.Owing to special properties such as thermal stability,chemical stability,and environmental persistence,they have been widely detected worldwide.At present,some progress has been made in research on the behavior of PFOA and PFOS in environmental media.This study summarized the progress of research on transport behavior of PFOA and PFOS in environmental media and related mathematical models.The mechanisms(electrostatic interactions,hydrophobic interactions,ligand exchange,and hydrogen bonding)and factors(organic matter content,mineral type,mineral content,medium moisture content,ion type,ionic strength,and pH)that affect the transport of PFOA and PFOS in environmental media,and mathematical models(convective-dispersive model,two site model,two-region model,continuous-distribution multi-rate model,multiprocess rate-limited mass-transfer model,and TOSD transport model)are discussed and summarized.This will provide a comprehensive reference basis for further scientific research.
