Energy-Efficient Electrochemical Oxidation of Perfluoroalkyl Substances Using a Ti4O7 Reactive Electrochemical Membrane Anode
Abstract
An energy-efficient Magnéli phase Ti 4 O 7 reactive electrochemical membrane (REM) was applied for the oxidation of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). Approximately 5-log removal of these compounds was achieved in a single pass through the REM with residence times of ∼11 s at 3.3 V/SHE for PFOA and 3.6 V/SHE for PFOS. The permeate concentrations of PFOA and PFOS were <86 and 35 ng L –1, from initial concentrations of 4.14 and 5 mg L –1, respectively. The highest removal rates were 3415 ± 203 μmol m –2 h –1 for PFOA and 2436 ± 106 μmol m –2 h –1 for PFOS at a permeate flux of 720 L m –2 h –1 (residence times of ∼3.8 s). The levels of energy consumption (per log removal) to remove PFOA and PFOS to below the detection limits were 5.1 and 6.7 kWh m –3, respectively. These values are the lowest reported for electrochemical oxidation and approximately an order of magnitude lower than those reported for other technologies (i.e., ultrasonication, photocatalysis, vacuum ultraviolet photolysis, and microwave–hydrothermal decomposition), demonstrating the promise of the REM technology for water treatment applications.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
