Scope

This document describes the method for determining the mercury content in lead concentrates.
This document is applicable to the determination of mercury content in lead concentrates. Method 1 is atomic fluorescence spectrometry, with a determination range (mass fraction): 0.000 10%~0.500%; Method 2 is solid sample direct injection, with a determination range (mass fraction): 0.000 001 0%~0.0250%.
For lead concentrates with a mercury content (mass fraction) range of 0.000 10%~0.025 0%, Method 2 is used as the arbitration method.
