Best Practices for Experimental Design, Testing, and Reporting of Aqueous PFAS-Degrading Technologies

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: May 1, 2025

Increased awareness of pervasive per- and polyfluoroalkyl substances (PFAS) contamination the need for zero-pollution treatment solutions necessitate scientific engineering community to respond urgently systematically. Existing approaches lack reproducible standardized methods report technological capabilities. Consequently, it is difficult compare innovations accurately assess their potential. In this Perspective, we shed light on hurdles encountered in lab-scale research development aqueous PFAS destruction technologies with a focus chemical offer recommendations overcoming them. Best practices are provided developing robust laboratory protocols covering crucial aspects such as experimental planning, sample storage analysis, waste management. Further, present five criteria standardize reporting performance advances degrading technologies: 1) scope, 2) defluorination efficiency, 3) relative energy consumption, 4) material stability, 5) unit process considerations. Through dissemination these insights, aim foster progress highly effective solutions.

New Insights into Thermal Degradation Products of Long-Chain Per- and Polyfluoroalkyl Substances (PFAS) and Their Mineralization Enhancement Using Additives

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

Published: Dec. 3, 2024

The products of incomplete destruction (PIDs) per- and polyfluoroalkyl substances (PFAS) represent a substantial ambiguity when employing thermal treatments to remediate PFAS-contaminated materials. In this study, we present new information on PIDs produced in both inert oxidative environments from five long-chain PFAS, including three now regulated under the U.S. Safe Drinking Water Act, one cationic precursor compound, C10 PFAS. data did not support generation tetrafluoromethane any studied carbonyl fluoride was found only potassium perfluorooctanesulfonate (K-PFOS) heated air narrow temperature range. Oxidative conditions (air) were observed facilitate PFAS degradation accelerate mineralization K-PFOS. Spectroscopic suggest that is initiated by cleavage bonds form perfluoroalkyl radicals, leading organofluorine (e.g., perfluoroalkenes). air, radicals react with oxygen oxygen-containing PIDs. enhanced adding solid additives, which categorized as highly effective granular activated carbon (GAC) certain noble metals), moderately effective, noneffective. Remarkably, simply GAC, achieved >90% perfluorooctanoic acid at 300 °C ∼1.9 atm within just 60 min without using water or solvents.

Thermochemical Recycling and Degradation Strategies of Halogenated Polymers (F−, Cl−, Br−): A Holistic Review Coupled with Mechanistic Insights

The Chemical Record, Journal Year: 2025, Volume and Issue: unknown

Published: April 7, 2025

Abstract Handling the waste associated with halogenated polymers is a daunting task due to well‐documented emission of halogen‐bearing toxicants during disposal or recycling operation. According Stockholm Convention treaty, most these products are classified as persistent organic pollutants their potential health hazards. This review aims provide holistic overview recent updates for treating polymeric through physical, chemical and biological approaches. In line inquiry, critical analysis obstacles prospects each degradation technique on polymer has been performed, assessing based efficiency, treatment upscaling, pollution control, feasibility. Though many treatments show promising results, they also entail drawbacks. Thermal exploiting various metal oxides, especially calcium additives, considered executable valorization coupled mineralization/metal extraction its intuitive operational feasibility scalability. Strategies combating soaring wastes summarized herein tap into promoting circular economy approach sustainable
