水中典型全氟化合物的吸附行为

Perfluorooctane sulfonate(PFOS) and perfluorooctanoate(PFOA) as the typical perfluoronated compounds(PFCs) are detected in various environmental compartments and organisms throughout the world.These compounds are persistent,toxic and bio-accumulative,which had potential threaten on the human's health.Since PFOS and PFOA are very stable,it is difficult to decompose them in ambient environments using the conventional methods.Obviously,it is crucial to control and remove this kind of compounds from water.Sorption has been proved to be an alternative technology to effectively remove PFOS and PFOA from water.This paper briefly discussed the species of sorbents and the effect of sorbents characteristic,solution chemistry,etc.on the sorption behavior and mechanism of PFOS and PFOA on some special sorbents basing on the previous reports.Finally,the potential prospects of developing and future research trends in this field are put forward.
