Reactivity of the singlet oxygen (SO), which is assumed to be one of the important oxidizers in natural waters, towards to a set of persistent herbicides, was measured for the first time using time resolved luminescence technique. It was observed that rate constants of SO reactions with the majority of studied herbicides are less than 106 M-1s-1 allowing to conclude about negligible participation of SO in oxidation of the compounds in natural waters.

单重态氧与水溶液中某些持久性除草剂的反应性的直接测量。

首次使用时间分辨发光技术测量了被认为是天然水中重要氧化剂之一的单线态氧（SO）对一组持久性除草剂的反应性。观察到，与大多数研究的除草剂发生的SO反应速率常数小于106 M-1s-1，从而得出结论：SO在天然水中对化合物氧化的参与可忽略不计。
