High iodine content in mineral salts affects the cell voltage

A new process has been developed now, namely the saltwater iodine removal device! Chongqing Sanyang Chemical likely has some information on this topic! It’s not clear yet whether they have iodine removal devices or not!
When iodide ions are present together with barium ions, Na3H2IO6 is formed, which has a significant impact on current efficiency and cell voltage, mainly due to the formation of particles that deposit within the membrane. Therefore, it is necessary to ensure that there is a certain amount of sulfate ions. Last edited by sister on 2009-2-21 15:05]
The high iodine content in the mineral salts not only affects the cell voltage but also causes a significant decrease in current efficiency; we suffer greatly as a result! :'(
Current saltwater treatment processes are ineffective against iodide ions, so it is best to avoid purchasing iodized salt. If there is a process to remove iodine, I personally think the cost is too high; it’s more affordable to use iodine-free salt.
We can use our adsorption method to remove iodide ions, and then the saline solutions can be combined again.
It is still necessary to control the source, and to strengthen the control of barium ions in saline solutions in order to avoid affecting amplification.
Is the salt solution used by the poster made by mixing mineral salt and sea salt? Can it be confirmed that the iodine comes from mineral salt rather than sea salt? Generally, the iodine content in sea salt is too high; so how does iodine end up in mineral salt? It’s not possible that food-grade salt was put in the wrong container, right? I would appreciate guidance from all the experts here.
