Persulfate-based degradation of perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) in aqueous solution: Review on influences, mechanisms and prospective
Abstract
Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) have attracted global attention due to their chemical durability, wide distribution, biotoxicity and bioaccumulative properties. Persulfate is a promising alternative to H2O2 for advanced oxidation processes and effective for organic removal. In this review, persulfate activation methods and operational factors in persulfate-based PFOA / PFOS degradation are analyzed and summarized. Moreover, the decomposing mechanisms of PFOA and PFOS are outlined in terms of molecular structures based a series of proposed pathways. PFOS could be converted to PFOA with the attack of SO4- and OH. And then PFOA defluorination occurs with one CF2 unit missing in each round and the similar procedure would occur continuously with sufficient SO4- and OH until entire decomposition. In addition, several knowledge gaps and research needs for further in-depth studies are identified. This review provides an overview for better understanding of the mechanisms and prospects in persulfate-based degradation of PFOA and PFOS.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
