Did you know that the aqua regia was first discovered by an Iranian chemist about 800 years ago which we are using it every day for digesting most of the chemicals to determine chemical composition.
Today, I was working in the lab trying to find out the best method to digest CRT glass with aqua regia! You won't believe it, no HF at all. Although some silicon remained at the end of the digestion process but the rest was digested. The success was in preparing the solution right before adding the fine powder of CRT glass. In this case, HNO3 and HCl recats and produce NOCl which is very strong and can attack the component and dissolve it.
Thanks to Jaber for his discovery!
