چکیده مقاله

Per- and polyfluoroalkyl substances (PFAS) have become a major concern in water and wastewater treatment due to their widespread occurrence, high chemical stability, and resistance to conventional degradation processes. Although technologies such as adsorption, ion exchange, and membrane filtration can effectively remove PFAS from aqueous systems, they mainly transfer contaminants into secondary waste streams rather than achieving complete destruction. Therefore, increasing attention has been directed toward emerging destructive technologies capable of degrading PFAS molecules and promoting defluorination. This review summarizes the current status of advanced PFAS destruction approaches, including electrochemical oxidation, photochemical and photocatalytic processes, sonochemical treatment, plasma-based technologies, and supercritical water oxidation. The fundamental principles, treatment capabilities, advantages, and limitations of these technologies are discussed, with emphasis on their potential applications in water and wastewater remediation. Despite promising results obtained at laboratory and pilot scales, several challenges, including high energy consumption, operational costs, scalability limitations, incomplete mineralization, and the formation of transformation products, continue to hinder their widespread implementation. Future research should focus on improving process efficiency, developing sustainable and energy-efficient treatment systems, and integrating separation and destruction technologies to achieve reliable PFAS remediation. These advancements are essential for transitioning from conventional PFAS removal strategies toward long-term and sustainable contaminant elimination.
