Radical and nonradical oxidative degradation of acetaminophen in ultraviolet light activated persulfate systems: comparison of PDS and PMS

was the predominant species in the UV/PMS system. Moreover, the intermediate products generated during the UV/PDS reaction were analyzed using liquid chromatography-mass spectrometry (LC-MS). This study demonstrated the feasibility of UV light-activated persulfate systems for ACE treatment, providing a systematic comparison of the performance and mechanisms of ACE degradation between the two systems. The findings offer valuable insights and practical guidance for selecting persulfates in UV light-activated research and applications.
