What is ISO 19976 ‑ 1 - Flame atomic absorption spectrometric method about?
ISO 19976 ‑ 1 specifies a flame atomic absorption spectrometric method for the determination of the mass fraction of cadmium in copper, lead and zinc sulfide concentrates as follows:
For copper sulfide concentrates, the method is applicable to the determination of mass fractions of cadmium from 0,01 % to 0,30 %
For lead sulfide concentrates, the method is applicable to the determination of mass fractions of cadmium from 0,01 % to 0,30 %
For zinc sulfide concentrates, the method is applicable to the determination of mass fractions of cadmium from 0,05 % to 0,30 %
