Efficient decomposition of perfluorooctane sulfonic acid in water using plasma and sulfate radical anions

摘要

H) is an excellent surface-active agent and has been widely used in various applications. However, PFOS is a bioaccumulating substance and has toxic effects on the human body. We recently found that plasma generated in gas bubbles can decompose PFOS very efficiently and rapidly [1]. During the PFOS decomposition process using plasma, perfluorocarboxylic acids (PFCAs: C
