Ultrafast PFAS degradation using oxidant-containing microdroplets

Abstract

Toxic PFASs usually require a long time and a high energy input for effective degradation. This study reports an ultrafast and effective method for degrading PFASs using microdroplets containing persulfate or Fenton's reagent. A 77–94% degradation efficiency was obtained for perfluorocarboxylic acids (PFCAs) in <1 ms under ambient conditions.
