Abstract: Perfluorinated compounds (PFCs) and their alternatives are fluorinated hydrocarbons, which are persistent, toxic, and bioaccumulative, posing potential threats to the biosystems and even human health. So far, several treating techniques including adsorption and electrochemistry for PFCs and their alternatives have been developed, yet their removal efficiencies and applications are extremely different. Moreover, little systematic review and comparative research is available about the treating techniques for PFCs and their alternatives. In order to screen a suitable and effective removal technique for PFCs and their alternatives, extensive details were summarized from treating techniques in recent years. Based upon the comparisons among the removal efficiencies, removal mechanisms, applicability, advantages, and disadvantages of those techniques, and further analysis of their developing trends, a scientific basis for the effective treatment of PFCs and their alternatives could be provided. -
