Hydrophobic Ion Pairing with Cationic Surfactant Modifies Surface Activity and Colloidal Behavior of PFAS
Quaternary ammonium compounds (QACs) are increasingly used to enhance the removal of per- and polyfluoroalkyl substances (PFAS), particularly short-chain compounds, through hydrophobic ion pairing (HIP). Here, we investigated how HIP with cetyltrimethylammonium chloride (CTAC) influences the interfacial and colloidal...
