DESTRUCTION OF PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS) WITH ADVANCED REDUCTION PROCESSES (ARPS): A CRITICAL REVIEW
Cui, J., P. Gao, and Y. Deng.
Environmental Science & Technology 54(7):3752-3766(2020)

Advanced reduction processes (ARPs) are a promising method to destroy PFAS in water due to the generation of short-lived and highly reductive hydrated electrons (eaq-). This review examines the mechanisms and performance of the electrons on the reductive destruction of PFAS and the unique properties of eaq- and its generation in ARP systems, particularly ultraviolet (UV)/sulfite and UV/iodide systems. It also compares the degradation mechanisms of different PFAS chemicals. The review concludes by identifying priority research needs.
