摘要
全氟烷基化合物(PFASs)是一类新型持久性有机污染物,具有环境持久性、生物蓄积性和毒性.近年来,PFASs引起的环境问题受到国内外学者的广泛关注和研究,与此同时,PFASs的去除技术也被广泛研究.现有的PFASs去除技术主要包括吸附、化学氧化、化学还原和生物降解等,因为反应机理和适用条件的差异,各种技术对PFASs的去除效果也有所不同.本文主要对不同PFASs去除技术的常用材料、反应效率、反应机理、能耗和影响因素进行了详细的阐述和对比,同时总结归纳了目前研究所存在的问题、面临的挑战以及未来发展的前景,以期为开发更高效的PFASs去除技术提供参考.
Perfluorinated allkyl substances(PFASs)are a new class of persistent organic pollutants with persistence,biotoxicity and bioaccumulation.Recently,PFASs related environmental issues have been widely concerned by worldwide scientists.Meanwhile,PFASs removal techniques including adsorption,chemical oxidation,chemical reduction and biological treatment have been widely studied.However,due to the differences of reaction mechanisms and applicable conditions,various techniques show different removal efficiencies on PFASs.In this study,the common materials,removal efficiency,reaction time,reaction mechanism,energy consumption and the influence factors of different treatment techniques were summarized and elaborated in detail.Moreover,the existing problems,challenges and future outlooks of current researches were summarized,so as to provide reference for the development of effective removal techniques of PFASs.
