标准范围

This document specifies an acid digestion and inductively coupled plasma atomic emission 
spectrometric (ICP-AES) method for the determination of the mass fraction of cadmium in copper, lead 
and zinc sulfide concentrates as follows:
a) for copper sulfide concentrates, the method is applicable to the determination of mass fractions of 
cadmium from 0,01 % to 0,30 %;
b) for lead sulfide concentrates, the method is applicable to the determination of mass fractions of 
cadmium from 0,01 % to 0,30 %;
c) for zinc sulfide concentrates, the method is applicable to the determination of mass fractions of 
cadmium from 0,05 % to 1,00 %.
