Researchers studied non-thermal atmospheric plasma (NTAP) decomposition of very low concentrations (< 1 µg/L) of perfluorinated compounds (especially PFOA and PFOS) present in wastewater produced during the process of cleansing contaminated soil. The efficiency of the NTAP decomposition process was investigated for air, oxygen, and nitrogen plasma, with exposure times of 1-10 min and different plasma nozzle and reactor sizes. In experiments NTAP treatment degraded > 50% of the initial PFC concentration in the water samples in < 200 s. The final concentration of perfluorinated compounds showed strong dependence on the tested parameters. http://www.mdpi.com/1996-1073/11/5/1290/pdf
