Implication

Review evaluates advanced strategies for PFAS degradation, highlighting challenges and future directions.

Key Points

  • This review aims to synthesize recent advancements in methods for degrading PFAS in water, emphasizing their effectiveness and limitations.
  • Synthesis of recent advancements in PFAS degradation mechanisms: oxidation-driven, biodegradation, reduction-driven, and nonradical processes.
  • Evaluation of treatment technologies based on defluorination, mineralization, byproduct risks, and operational stability.
  • Assessment of practical implementations for high-strength PFAS wastes versus emerging laboratory-stage systems.
  • Oxidative and reductive systems can achieve rapid degradation but face performance limitations due to radical quenching and structural sensitivity.
  • Biodegradation methods show mild transformation potential, yet they suffer from slow kinetics and narrow substrate specificity.
  • Electrochemical oxidation and thermochemical processes are nearing practical application, while many photocatalytic methods remain in research stages.
