Abstract
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous, recalcitrant, bioaccumulative, and toxic. Effective concentration technologies are essential for remediating these compounds, a major focus of environmental science and engineering today. This review provides a comprehensive overview of PFAS, from fundamental chemistry to current research, encompassing fluorine chemistry, PFAS synthesis, and their applications. The review specifically thoroughly examines how fluorine chemistry can be utilized to enhance PFAS removal and enrichment, highlighting examples of aromatic/direct fluorination and aliphatic per- and polyfluorination, where the latter induces the fluorous effect. A comprehensive list of reactions used to design or modify PFAS sorbents is summarized, serving as a resource for ongoing research. Finally, insights are offered into how fluorine chemistry can be studied and employed to further improve PFAS characterization and management.
期刊介绍：
ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
