Abstract

A continuous gas–liquid flowing film reactor with a nanosecond-pulsed power supply was utilized for the degradation of perfluorooctanoic acid (PFOA) as assessed by fluoride (F⁻) formation. PFOA, 50 mg/L, dissolved in deionized water was supplied at 2 ml/min with an argon carrier gas. The liquid phase was analyzed for F⁻ using ion chromatography. The power supply pulse frequency (f) was varied between 0.25- and 10-kHz using a constant 16-kV input voltage and 40-ns pulse width. The highest F⁻ production rate ((Formula presented.)), 1.57 × 10⁻⁸ mol/s, occurred at 5 kHz whereas the highest efficiency of F⁻ production ((Formula presented.)), 9.12 × 10⁻⁹ mol/J, was found at 0.25 kHz.
