Amonia Solution For Aqua Regia

[mustu4u]

Dear Sir,

I have an electroplating business in India and i use 24 ct Gold for plating.
I used to make my own Gold Potassium Cynaide (GPC) using Aqua Regia method.

My question is, is there any better option for nuetralising Aqua regia solution by Ammonia Solution (Aq) ???

While you do this, you can tell us your process in all details. It sounds really dangerous, but maybe I have misunderstood you.

i believe there is a misunderstanding. aqua regia is an acidic solution. any type of cyanide introduced would form hydrogen cyanide gas. your first plating solution would have been your last if i understand it correctly.
