摘　　要：全氟及多氟化合物中氟表面活性剂类物质的大量生产和使用,导致其在水环境介质中广泛检出.由于氟表面活性剂具有持久性、累积性和高毒性,研发其高效处理技术对于控制其环境及健康风险具有重要意义.鉴于C—F键的强稳定性,活性炭吸附是目前最适用的处理技术之一.本文详细阐述了氟表面活性剂的特性、吸附作用机制及活性炭物化性质对其吸附性能的影响,可为氟表面活性剂吸附机理的研究及高效活性炭吸附材料的研发提供科学指导.Fluorinated surfactants as a major subgroup of per-and polyfluoro alkyl substances which has been extensively produced and applicated,are widely detected in aquatic environment.Due to its persistence,cumulativity and high toxicity,it is necessary to develop high efficiency treatment strategy.Given the strong stability of the C—F bond,activated carbon adsorption is one of the most practical technologies.In this review,we provide an overview of the aqueous solution and self-assembly properties of fluorinated surfactants,the adsorption mechanism of fluorinated surfactants and the effects of activated carbon physical/chemical properties on its adsorption,which could offer some fundamental knowledge on its adsorption mechanism and carbon materials design in the future research.
