Summary:
Due to the large variety of per- and polyfluoroalkyl substances (PFAS) with varying properties and stringent cleanup standards, water treatment has posed a challenge. Here, we introduce a method utilizing colloidal gas aphrons (CGAs or "aphrons") to treat PFAS-contaminated water. This approach is not only effective in removing long-chain PFAS but also excels in targeting the more difficult-to-remove short-chain PFAS. Given that aphrons are already widely used in the wastewater treatment industry, adapting this technology for PFAS remediation represents a promising and practical solution for addressing PFAS in impacted water streams.
