Topic: Boric acid consumption in nickel plating tank
We have a nickel sulfamate tank which showed a significant drop in boric acid concentration in a matter of a few days. It went from 36 g/L to 30 g/L and we are not sure why. The pH is stable but the nickel concentration also dropped. Are the nickel and boric drops coincidental or consequential? Has anyone seen this kind of drop before? I'm not as concerned about the nickel concentration drop because we are aware of the cause of that. More concerned about the boric. Any help is appreciated. Thank you.....
