要約(英語): Perfluorooctane sulfonate is persistent and useful substance; however energy efficient decomposing methods are urgent needs due to the toxicity of prolonged exposure of PFOS. PFOS in solution cannot be decomposed by hydroxyl radicals but easily decomposed by plasma generated on or in the solution. The voltage polarity is one of the unknown parameters for PFOS decomposition using plasma. Experimental results showed that the plasma sustaining voltages and the decomposition rate of PFOS were not affected by the voltage polarity; however the decomposition energy efficiency and by-product generation quantity was affected by the voltage polarity. Two types of decomposing processes was proposed according to the voltage polarity.
