英文摘要The influence factors and mechanism of the degradation of ofloxacin in water by electron linear accelerator was investigated. In order to study the role of radicals, ofloxacin solution with initial concentration of 20mg/L was used in degradation with the doses of 0.5, 1.0, 2.0, 3.0 and 5.0 kGy, respectively, for each of different conditions. The solution were saturated with air as a scavenger of hydrated electron, saturated with nitrogen, containing 0.005 mol/L sodium chloride, 0.05 mol/L sodium chloride, 0.05 mol/L tert-butanol as scavenger of hydroxyl radical, 0.005 mol/L sodium carbonate, and 0.005 mol/L sodium sulfate, respectively. It was found that the degradation rate was promoted under the condition of saturated air, and could reach 99% with irradiation dose of 2.0 kGy. The presence of sodium chloride, tert butyl alcohol and sodium carbonate significently inhibited the degradation rate of ofloxacin, however, sodium sulfate had little effect on the degradation. This fact indicates that hydroxyl radicals play a key role in the degradation of loxacin. Based on the product analysis in irradiation by ultra performance liquid chromatography-mass spectrometry (UPLC-MS), the degradation pathway has be deduced as well. 漏 2016, Editorial Board of China Environmental Science.
