Excess chloride ions in the electrolyte~! Is there a way to deal with it?
Thread Content
The chlorine content in my electrolyte is currently 0.35 g/L. The peeling of the lead anode is quite severe. Please, help me out, Heyou~! ~!
Divert it; it’s the only option. Eliminate it at the source again
Eliminate chloride ions at the source by diverting them for treatment
If it is zinc smelting, such chlorine levels should not have a significant effect on the lead anodes. It is recommended that the person in question analyze the reasons by examining the quality of the plates and the conditions under which electrolysis takes place
Good methods for dechlorination, ccfei421@126.com
Are you referring to the chlorine content in the zinc smelting electrolyte? Liquid dechlorination can be considered.
Chlorine removers can be added; contact ike5@163.com
Adding silver sulfate can solve it! Calculate the amount of silver sulfate to be added based on the amount of chloride ions, and then filter it.
The most likely approach is to carry out regular open-circuit tests; if the raw materials contain too high levels of chlorine, it is necessary to plan for the use of alternative methods or to find a manufacturer that uses the ammonia process for zinc electrolysis
Chlorine removal using copper slag can be considered, and the results are quite good
