[0002] Ammonia desulfurization is a commonly used desulfurization method in industrial production. Ammonia is usually used as an absorbent to react with SO2 in the flue gas to produce ammonium sulfite, which is then oxidized to produce stable ammonium sulfate. In this process, oxidation rate detection is required to determine whether all the ammonium sulfite produced by the absorbent has been oxidized.
[0003] Oxidation rate detection is a key step in industrial production for evaluating and controlling chemical reaction processes. Currently, oxidation rate detection is mainly carried out by sampling titration. Although this method can meet the needs of oxidation rate detection to a certain extent, it has the following disadvantages:

The sampling process is cumbersome, complex, labor-intensive, time-consuming and error-prone. Moreover, since the sampling titration method requires a certain amount of time to complete the processing and analysis of the sample, the oxidation rate detection results have a certain lag and cannot reflect the oxidation status of the production process in real time. In addition, the sampling titration method requires the use of a large amount of chemical reagents, which not only increases production costs, but also has a certain impact on the environment.
