| Abstract: | At present,the ubiquitous occurrence of perfluorooctanoic acid(PFOA)and perfluorooctane sulfonic acid(PFOS)has resulted in global environmental pollution and caused worldwide concerns.Owing to their stability,persistence and bioaccumulation,PFOA and PFOS are difficult to be degraded by using conventional methods,such as ultrasonic degradation,electrochemical oxidation or microbial degradation.Therefore,development of effective technologies for decomposing PFOA and PFOS into harmless species is now the research priority.Currently,the great potential and excellent application prospects of photodegradation technology on the PFOA and PFOS degradation have received considerable attentions from the researchers.Here we systematically summarized the domestic and overseas studies on the photodegradation of PFOA and PFOS done in recent years.The photodegradation efficiencies and mechanisms of PFOA and PFOS with different catalysts,oxidants,or photosensitizer were reviewed in details.The possible problems and application potentials of the PFOA and PFOS photodegradation technology were systematically discussed.The aim of this review is to provide comprehensive information for the development of effective and safe photodegradation technology for PFOA and PFOS degradation,and provide scientific guidance for the direction of these technologies. |
