Hydrophobic Ion Pairing with Cationic Surfactant Enhances the Octanol–Water Distribution Coefficient of PFAS
Cationic additives are increasingly used to enhance per- and polyfluoroalkyl substances (PFAS) removal, particularly for short-chain PFAS; however, the mechanisms underlying this enhancement remain poorly understood. Here, we quantitatively evaluate how hydrophobic ion pairing (HIP) with cationic additives alters PFA...
