[Case Study on the Use of Conductive Diamond Technology] Decomposition of PFAS by Electrolytic Oxidation Method

Decomposition of PFAS through electrochemical oxidation using the power of diamonds.

Chemically stable and considered difficult to decompose, organic fluorine compounds (PFAS). The method we propose for their treatment is an electrochemical decomposition method using diamond electrodes. The extensive potential window of diamond electrodes efficiently generates reactive species such as ozone (O₃) and hydroxyl radicals (•OH), which have extremely strong oxidative power during the electrolysis of water. These reactive species strongly attack and cleave the chemical bonds of PFAS, breaking them down into harmless substances. Additionally, when sulfuric acid is used as the electrolyte, peroxodisulfate (S₂O₈²⁻) is generated due to the action of the diamond electrode. This powerful oxidizing agent has also been reported in recent studies to significantly contribute to the decomposition of PFAS, attracting attention.
