🔬 In a recent article published in Nature Magazine — Breaking strong carbon–fluorine bonds for recycling — fluorine chemistry specialist Véronique Gouverneur and her group at the University of Oxford, together with Robert Paton from the Department of Chemistry at Colorado State University, describe a discovery as unexpected as it is promising in the field of PFAS treatment — those notoriously persistent fluorinated compounds in the environment.
🧠 Why unexpected?
The breakthrough uses a novel approach: mechanochemistry — initiating chemical reactions through mechanical force in a ball mill, rather than in traditional solution-phase chemistry.
This innovation was inspired by an anomaly observed during a previous study aimed at synthesizing fluorinated compounds from fluorite (fluorspar), avoiding the use of hydrofluoric acid (HF) — a highly dangerous and corrosive chemical. 💡 This anomaly was ingeniously identified and exploited, opening the way to an entirely new technology.
🚀 A Promising Solution
The result is a dry mechanochemical mineralization process that successfully breaks carbon–fluorine bonds, among the strongest in organic chemistry.
1️⃣ The method allows for complete degradation, avoiding the formation of other PFAS as by-products — which are often just as undesirable or even more toxic. 2️⃣ It works on a wide variety of PFAS compounds. 3️⃣ It opens the way to fluorine recovery and recycling for the synthesis of new fluorinated chemicals.
♻️ This approach is a game-changer: instead of destroying PFAS, it could allow their valorization, laying the groundwork for a circular economy for fluorinated compounds. An unprecedented development.
🙏 Let us hope this process proves viable at scale and can be transferred to industry — a vital step in addressing the major environmental challenges linked to PFAS pollution.
