Yes, divide the nickel metal by 0.234 to calculate the nickel sulfamate. Thanks.

So I can do a calculation.

Ni metal / 0.234 or

Ni metal x 4.30

Cool info guys.

Back to the original topic: Do you want to know the procedure for analyzing for the sulfamate ion or simply estimating it with a calculation like what Skelton suggested?

Right on, Paul! That is interesting stuff!!

So, after over 50 years, we may have just made a little bit of history in metal finishing via the Internet. Next time dcelletti or anyone searches the Net for the Ni metal concentration of Nickel Sulfamate, they may just trip up on this FinishingTalk.com posting and get their answer. Now that's pretty cool!

When I get a chance, I think I will scan and post that page from the MF Guidebook. Then, we can maybe help out the next inquiry regarding metal concentration of all metal salts.

Cheers.

Hey Skelton - check this out. I just read your posting and did a quick search on Ni Sulfamate I found this info..... It is from the NMFRC website, and is a paper that was given at Sur-Fin 1954! It doesn't necessarily talk about the analysis asked for in the original posting - but Its still pretty interesting.

Nickel Plating From the Sulfamate Bath

Presented at the Forty-First Annual Convention of the American Electroplaters Society, July 13, 1954.

Richard C. Barrett, Barrett Chemical Products Company, Shelton, Connecticut.

HISTORIC
Nickel plating from sulfamate solutions was first announced in 1938 by Piontellil and Cambri in Italy. Although Piontelli and his co-workers continued to report regularly upon their progress of plating from sulfamate solutions during the subsequent ten years, the bulk of their research was confined to the development of bath formulae for plating or electrowinning of lead.

Co-incidental with the announcement of a commercial source of production of sulfamic acid in this country during the late 1930’s, further interest was aroused domestically and several descriptions only of laboratory interest were published by Choguill, Mathers, and Forney. In 1940 a patent was issued to Cupery15 covering the plating of copper, nickel, and lead from sulfamate electrolytes.

Hello Dcelletti, Thanks for your post on finishingtalk.com. I apologize for the delay in getting back to you, a colleague of mine forwarded this post to me to answer yesterday and I am just now getting to it. To be honest, I should thank you, I recently moved and this promoted me to go out to my storage and dig out my ol' Metal Finishing Guidebook(s). I could have told you if it were nickel chloride or maybe nickel sulfate, but when I saw sulfamate, I honestly scratched my head. Not wanting to revisit the molecular weight and then divide the m.w. of nickel by the m.w. of the sulfamate ion, knowing exactly where to find this chart in my MF Guidebook made this a much easier task.

Here is your answer, and then some:

Nickel Sulfamate Ni(NH2SO3)2 = 23.4% Ni metal

Nickel Chloride NiCl2-6H2O = 24.7% Ni metal

Nickel Sulfate NiSO4-5H2O = 22.3% Ni metal

Thanks again for posting on finishingtalk.com!!!

And Happy Holidays!!

Skelton

Ni Sulfamate analysis calculation

I have a Ni Sulfamate plating solution and have the Ni metal concentration. I would like help getting a concentration for the Ni sulfamate in oz/gal. Does anyone know a calculation or analysis I can use?
