EPR spectroscopy was applied to obtain qualitative and quantitative information on the radicals produced in disinfection processes of wastewater for agricultural reuse. The DEPMPO spin trap was employed to detect hydroxyl and carbon-centered short living radicals in two different peracetic acid solutions and a hydrogen peroxide solution used for water disinfection either in the absence or in the presence of UV-C irradiation. Moreover, three different kinds of water (wastewater, demineralized water, distilled water) were analysed in order to assess the contribution of Fenton reactions to the radical production. The spectroscopic results were discussed in relation to the efficiency of the different oxidizing agents and UV irradiation in wastewater disinfection evaluated as Escherichia Coli, Faecal and Total Coliforms inactivation.
电子顺磁共振光谱法被用于获取农业回用废水消毒过程中产生的自由基的定性和定量信息。采用DEPMPO自旋捕集剂来检测两种不同过氧乙酸溶液以及一种用于水消毒的过氧化氢溶液（无论有无紫外线C照射）中以羟基和碳为中心的短寿命自由基。此外，分析了三种不同类型的水（废水、去离子水、蒸馏水），以评估芬顿反应对自由基产生的贡献。结合不同氧化剂和紫外线照射在废水消毒中的效率（以大肠杆菌、粪便和总大肠菌群的灭活情况来评估）对光谱结果进行了讨论。
