电化学氧化/还原技术降解水中全氟和多氟烷基化合物研究进展
Research progress on electrochemical oxidation/reduction for degradation of per-and polyfluoroalkyl substances in water
摘要
Abstract
Per-and polyfluoroalkyl substances(PFASs)are characterized by wide sources,easy migration,easy accumulation,and high toxicity.Moreover,the C—F in their molecules is so stable that it makes PFASs difficult to be effectively removed from water by traditional treatment techniques.However,electrochemical technology can realize redox degradation of PFASs by generating active species(·OH and H*)through direct or indirect electron transfer.In this paper,the research progress was presented on the PFASs degradation based on a single electrochemical oxidation/reduction technology,including degradation mechanism,electrode material development,and technology optimization.Then,a summarization was given on the degradation effect and technological advantages of the electrochemical technique combined with(Fenton-like)Fenton,persulfate,and photocatalysis.Finally,an outlook was made for the PFASs degradation by electrochemical technology.关键词
