The first time I actually saw Ferric Chloride used in an industrial
application was in a wastewater treatment system! I asked what it
was used for and they told me that it was used to precipitate out
other chemicals (if I remember correctly). I was also supprised that
the ferric chloride was stored/used in a very large open topped poly
tank.
Closer to topic....
I too am wanting to try regenerating some of my used ferric chloride
using the iron nail - Power supply method.
Is there any way to know when to stop the plating process or is this
simply trial and error at this point????
