GB/T 6150.15-2023 Methods for chemical analysis of tungsten concentrates—Part 15:Determination of bismuth content—Hydride generation atomic fluorescence spectrometry and flame atomic absorption spectrometry
Abstract
This document specifies the method for determining the bismuth content in tungsten concentrates.
This document is applicable to the determination of bismuth content in tungsten concentrates, and includes hydride generation atomic fluorescence spectrometry (Method I) and flame atomic absorption spectrometry (Method II). The determination range (mass fraction) of Method I is 0.001% to 0.30%, and the determination range (mass fraction) of Method II is 0.050% to 0.50%. When the determination ranges overlap, Method II shall be used as the arbitration method.
