Dear John: Most vendors receive inquiries such as yours quite frequently. There are many well meaning individuals who would like to plate various objects, usually as a hobby. I must urge you and others to use extreme caution. Always make very sure that you are qualified and trained to use some of the chemicals that we use in various chemical baths. Some are irritants, some are toxic, and all must be handled with the utmost care.

Finally, John, as with all responsible platers, you must legally discard any wastes that you generate. In most cases, that means either waste treatment and the legal discarding of any sludges. We as members of the Electroplating community work very hard every day to be good neighbors. Gone are the days of industry several decades ago, where waste treatment was a thing of the future. Stay with plating, learn all that you can. And, yes -you can join the American Electroplaters Society to learn more about plating.

Dear Sirs, I am a research student (chemistry). I am curious to know what chemicals are used as brighteners in zinc & nickel electroplating?

Hi, Vijaykumar. The relevant chapter of ASM's Metals Handbook, Volume 5: Surface Engineering, will give you very good insight into this subject, including the wetting agents, the carriers, and the primary and secondary brighteners. But that is pretty much old news, basically for research. Today nearly all plating shops use proprietary brighteners which are trade secret. Good luck.
