Components contained in the brackish water exiting the tank

I would like to ask everyone a question: in the brine that comes out of the cell during ion-exchange membrane soda production, what components are increased as a result of side reactions occurring in the electrolytic cell and the dissolution of chlorine? Personally, I think the following have been added: HCL, HCLO, NaCLO, NaCLO3, CL2 – I’m not sure if this is correct Another point is whether HCLO and NaCLO remain in the brine water exiting the tank If coexistence is the case, then why does the laboratory, when conducting a comprehensive analysis of brackish water, report only the result for NaCLO and not for HCLO? Could it be that the result for NaCLO is a combination of HCLO and NaCLO? # ， ， &
1. When discussing the saltwater exiting the membrane, reference is generally made to the free chlorine content, which varies significantly depending on the duration of membrane use and the type of membrane. Generally, at the beginning of membrane operation, there are fewer side reactions, so the free chlorine content is low; as the electrochemical performance of the membrane deteriorates, the free chlorine content increases； 2. When analyzing the content of chlorates, the influence of free chlorine is generally eliminated (using ferrous sulfate or potassium iodide); it is not the same concept.
