Remove ammonia from electroplating nickel

2006

My problem is that my electroplating nickel has been contaminated with Electroless Nickel.
Any of you know how to remove it from the electroplating nickel?
I have tried at laboratory with high pH, KMnO4, "natrium hypochloride", iron sulfur. None of them has work.

Hi There,

how do you determine the ammonium contamination? Maybe you should try a dummy plating with higher voltage.

Its probably easier to dump the bath and start again. Oxidising ammonia ⇦ on eBay or Amazon [affil link] to nitrogen is not easy and will probably put everything else out of specification. Oxidising ammonia to anything else will only result in more problems.

Ammonia is not removable from a nickel bath. Try to cut the bath to an acceptable level.
