Scope
This document describes the method for determining the lead content in bismuth concentrate. It contains three methods: Method 1 (Na2EDTA titration method), Method 2 (Na2EDTA back titration method) and Method 3 (flame atomic absorption spectrometry). This document is applicable to the determination of lead content in bismuth concentrate. The determination range of Method 1 and Method 2 is: >5.00%～17.00%. The determination range of Method 3 is 0.10%～5.00%. Method 1 in this document is not applicable to the determination of lead content in bismuth concentrate containing more than 0.6% barium.
