Existing methods for PFAS removal require a long time and high energy input to achieve high degradation efficiencies. This study reports a novel, ultrafast and effective method for degrading PFASs using the microdroplet technique. By forming microdroplets from PFAS solution spiked with oxidant such as sodium persulfate or Fenton’s reagent, a range of PFAS compounds including short-chain perfluorocarboxylic acids (PFCAs) such as PFPeA (C4F9COOH) were quickly degraded with degradation efficiency reaching 77-94%. The microdroplet reaction was completed in less than 1 ms under ambient conditions. In contrast, without oxidant, the microdroplet degradation efficiency was 10-17%. Also, incubating PFAS with the oxidant in bulk solution for 30 min resulted in < 9% degradation efficiency. It appears that the PFAS degradation rate can be accelerated by over 2 million times in oxidant-containing microdroplets in comparison with the bulk solution. Based on the measured fluoride product concentrations, our result suggests that persulfate primarily facilitates PFAS degradation via the two-carbon degradation pathway, whereas Fenton’s reagent operates through the one-carbon degradation pathway. Overall, this study presents a new approach to PFAS degradation, offering valuable insights for developing effective PFAS removal strategies.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"18 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145195360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
