A review of electrochemical reduction processes to treat oxidized contaminants in water

International audience; This purpose of this review is to provide a short overview of electrochemical reduction processes for oxidized contaminants in water. The major parameters affecting the electro-reduction mechanisms and the impact of electrode choice are discussed with reference to both inorganic and organic pollutants that are either regulated or emerging (e.g., non-metal oxyanions, per-and polyfluoroalkyl substances (PFAS)). To conclude, a discussion is presented on the future directions and challenges that must be addressed to develop these electrochemical reduction processes at a larger, commercialized scale.
