AB  - High resolution mass spectrometry (HRMS) was coupled with ultra-high-performance 
      liquid chromatography (uHPLC) to monitor atrazine (ATZ) degradation process of 
      Fenton/ultrasound (US) treatment in real time. Samples were automatically taken 
      through a peristaltic pump, and then analysed by HPLC-HRMS. The injection in the 
      mass spectrometer was performed every 4 min for 2 h. ATZ and its degradation 
      metabolites were sampled and identified. Online Fenton experiments in different 
      equivalents of Fenton reagents, online US experiments with/without Fe(2+) and 
      offline Fenton experiments were conducted. Higher equivalents of Fenton reagents 
      promoted the degradation rate of ATZ and the generation of the late-products such 
      as Ammeline (AM). Besides, adding Fe(2+) accelerated ATZ degradation in US 
      treatment. In offline Fenton, the degradation rate of ATZ was higher than that of 
      online Fenton, suggesting the offline samples were still reacting in the vial. 
      The online analysis precisely controls the effect of reagents over time through 
      automatic sampling and rapid detection, which greatly improves the measurement 
      accuracy. The experimental set up proposed here both prevents the degradation of 
      potentially unstable metabolites and provides a good way to track each 
      metabolite.
