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 (
), 1.57 × 10−8 mol/s, occurred at 5 kHz whereas the highest efficiency of F− production (
), 9.12 × 10−9 mol/J, was found at 0.25 kHz.
