摘　　要：非均相类芬顿氧化技术被认为是极具前景的水处理技术之一,但在实际应用中仍面临氧化剂利用率低以及水基质消耗严重的限制.近年来,以单线态氧(^(1)O_(2))为主要氧化物种的类芬顿反应,因强亲电性、较长的半衰期和较强的环境抗干扰性能,在选择性降解复杂废水中的目标污染物方面展现出独特优势.本文首先系统总结了类芬顿反应中^(1)O_(2)的生成机制,阐述了影响^(1)O_(2)选择性生成的关键因素;其次,深入分析了多种用于检测和识别^(1)O_(2)非自由基的方法,指出了它们在定性和定量方面的优势与不足,并提出了相应的对应策略;最后,介绍了^(1)O_(2)主导的类芬顿技术在水质净化中的应用进展,并探讨了该研究领域面临的挑战及未来的发展趋势.Heterogeneous Fenton-like oxidation technology is considered one of the most promising water treatment methods.However,its practical application is limited by the low utilization efficiency of oxidants and significant consumption by water matrices.Recently,Fenton-like reactions that generate singlet oxygen(1O2)as the primary reactive species have demonstrated unique advantages in selectively degrading target pollutants in complex wastewater due to its strong electrophilicity,relatively long half-life,and robust environmental resistance.This paper systematically summarizes the generation mechanisms of^(1)O_(2)in Fenton-like reactions and elucidates the key factors influencing the selective generation of 1O2.Various non-radical detection and identification methods for^(1)O_(2)are then thoroughly analyzed,highlighting their qualitative and quantitative strengths and weaknesses along with corresponding strategies.Finally,the progress in applying 1O2-dominated Fenton-like technologies in water purification is reviewed,and the challenges and future trends in this research field are discussed.
