| چکیده مقاله |
| Cold plasma-based advanced oxidation processes (AOPs) have emerged as one of the most promising technologies for addressing persistent and complex pollutants in modern water and wastewater treatment. Unlike conventional AOPs that require chemical additives or external oxidants, cold plasma systems generate a diverse range of reactive oxygen and nitrogen species (RONS) directly at the plasma–liquid interface, enabling rapid and broad-spectrum degradation of organic contaminants. These systems exhibit strong oxidation potential, high treatment versatility, and the ability to mineralize compounds that are typically resistant to biological or chemical oxidation, such as pharmaceuticals, per- and polyfluoroalkyl substances (PFAS), and industrial dyes. In recent years, innovations in reactor design, plasma–catalyst coupling, and persulfate activation have significantly improved degradation efficiency and energy yield. Hybrid configurations combining plasma with catalysts, oxidants, or microbubbles further enhance process robustness and scalability. Despite these advances, challenges remain in optimizing energy consumption, ensuring plasma discharge stability, and managing transformation by-products. Economic feasibility and long-term environmental safety assessments are also critical for large-scale adoption. This review provides a comprehensive analysis of the mechanistic principles, treatment performance, and limitations of cold plasma-based AOPs, emphasizing their potential role in next-generation water treatment infrastructure. It also highlights future research needs in reactor optimization, cost reduction, and environmental risk assessment to enable sustainable and industrial-scale deployment. |
