Kinetics of Aqueous Persulfate-Induced Oxidative Degradation of Heptafluorobutanoate, Pentafluoropropionate, and Trifluoroacetate

•Kinetics of reaction of small perfluorocarboxylates with persulfate are presented•Perfluorobutanoate and propionate are faster to react than trifluoroacetate•Recombination to perfluoroalkanes observed at higher concentrations The kinetics of reaction of three fluorinated carboxylates (heptafluorobu...
