| Research Abstract |
Plasmas in bubbles have successfully demonstrated energy-efficient and fast decomposition of perfluorocarbons; such as perfluorooctanoic acid and perfluorooctanesulfonic acid, which are environmentally harmful and persistent substances. 20~100 mL solutions at 50 mg/L concentration of perfluorocarbons were completely decomposed after 3~8 hours of operation with the plasma generated in bubbles. Higher decomposing rate and energy-efficiency were obtained compared with other reported methods.
