Is there a connection between chlorates in saltwater and oxygen in chlorine?
Thread Content
After a shutdown in March, the oxygen content in chlorine decreased from 0.73% before the shutdown to 0.69% after it resumed operation. Although it’s within the acceptable error range, our managers are idiots (A-C); they won’t overlook even a 0.01% change. The chloride content in the brine also decreased, from 2.5 g/L to 2.2 g/L. All other conditions of the electrolyzer remain unchanged; the current (at full load), the amount of acid added, and so on are all the same as before shutdown. Is there a relationship between the oxygen content in chlorine and the chlorate content in the feed brine? What is this relationship, and what other factors influence the oxygen content? Be more specific
Personally, I don’t think there’s any connection between them. First, it’s necessary to understand how oxygen comes about and how it is generated; only then can we talk about whether the presence of oxygen in chlorine is related to chlorates. Clearly, these two things have nothing to do with each other. Besides, your indicators are within the normal range.

First of all, your leader is a careful and prudent good leader who pays close attention to even the slightest changes. There is a direct relationship between chlorates and the oxygen content in chlorine: the higher the concentration of chlorates in seawater, the higher the oxygen content in chlorine. This is because oxygen is a by-product of electrolysis at the anode involving chlorate ions; the oxygen evolution potential for chlorate ions is lower than that for chloride ions, so oxygen is produced more easily under the same conditions.
