| Abstract: | Sulfides have complex matrix,dramatically varied mineral composition and high content of sulfur and most of sulfides are often insoluble,which results in low precision and accuracy in trace elements determination.Several kinds of acid group were used to digest sulfide samples.On the basis of analysis,(A) HNO3 sealed digestion method;(B) HCl+HF and HNO3 two-step digestion method were used to further digest national standard sulfide and reference materials: GBW07267(pyrite),GBW07268(chalcopyrite) and GBW07270... |
