介绍了几种测定二氧化氯产生和投加过程中残余活性氧化剂的方法，包括碘量法、特定分光光度法和电位法。还讨论了运行中的连续控制，可以确定水中残留浓度的重要性。包括19个参考文献、图表。

Several methods for determining residual active oxidants involved in the generation and dosing of chlorine dioxide are described, including iodometry, specific spectrophotometric methods, and potentiometry. Continuous control in operation is also addressed, and it is possible to determine the significance of residual concentrations in water. Includes 19 references, figures.
