The growing diversity and prevalence of contaminants emerging concern (CECs) in aquatic environments present significant risks to human health ecosystems, necessitating the development effective remediation strategies. Advanced oxidation processes (AOPs) have emerged as a promising solution due their ability produce highly reactive species that efficiently degrade persistent contaminants. Among various oxidizing agents, peracetic acid (PAA) has attracted attention field water treatment for its powerful oxidative properties, environmentally safe decomposition, ease use. This article is designed offer comprehensive overview latest trends PAA-based AOPs. discussion begins with an intrinsic performance PAA, emphasizing potential degradation mechanisms. Subsequently, effectiveness AOPs remediating CECs explored, focusing on transition metal-mediated activation (Fe, Co, Mn), UV irradiation, carbon-based catalysts, all which enhance generation (RS). Next, determination RS examined, distinguishing between free radical (organic inorganic) non-radical (singlet oxygen high-valent metal) mechanisms govern pollutant degradation. Then, key factors affecting removal AOPs, including initial PAA concentration, catalyst dosage, pH, are also addressed. Following that, by-products hazard assessments associated discussed. Finally, current challenges future research directions proposed facilitate large-scale application remediation.
