Understanding the Selective Removal of Perfluoroalkyl and Polyfluoroalkyl Substances via Fluorine–Fluorine Interactions: A Critical Review

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 12, 2024

As regulatory standards for per- and polyfluoroalkyl substances (PFAS) become increasingly stringent, innovative water treatment technologies are urgently demanded effective PFAS removal. Reported sorbents often exhibit limited affinity frequently hindered by competitive background substances. Recently, fluorinated (abbreviated as fluorosorbents) have emerged a potent solution leveraging fluorine-fluorine (F···F) interactions to enhance selectivity efficiency in This review delves into the designs applications of fluorosorbents, emphasizing how F···F improve binding affinity. Specifically, existence results removal efficiencies orders magnitude higher than other counterpart sorbents, particularly under conditions. Furthermore, we provide detailed analysis fundamental principles underlying elucidate their synergistic effects with sorption forces, which contribute enhanced efficacy selectivity. Subsequently, examine various fluorosorbents synthesis fluorination techniques, underscore importance accurately characterizing through advanced analytical methods, emphasize significance this interaction developing selective sorbents. Finally, discuss challenges opportunities associated employing techniques guide design advocate further research development sustainable cost-effective interactions.

Poly- and perfluoroalkyl substances (PFAS) are a class of persistent organic pollutants whose high stability appreciable water solubility have led to near-global contamination. PFAS bioaccumulative toxins that been linked myriad disorders detected nearly universally in human blood. Liquid chromatography-tandem mass spectrometry is the most frequent method used for quantitation, though this typically only measures few dozen >14 000 known has shown account small portion total fluorine present. Sum parameter methods such as total, extractable, adsorbable emerged alternative measurements determination. Combustion ion chromatography become preferred organofluorine measurement where sorbent or extract containing combusted emitted hydrofluoric acid (HF) measure cumulative Herein we critically review types measurement, their separation from sample matrix, key parameters analytical instrument affect sensitivity, reproducibility, recovery with regards analysis.
