GB/T 6150.4-2023 Methods for chemical analysis of tungsten concentrates—Part 4:Determination of sulfur content—High frequency-infrared absorption method and combustion-iodometric method
Abstract
This document describes the method for determining the sulfur content in tungsten concentrates. This document is applicable to the determination of sulfur content in tungsten concentrates and includes two methods (Method I: High-frequency induction infrared absorption method; Method II: Combustion iodine titration method). The determination range (mass fraction) of Method I is 0.10% to 4.00%; the determination range (mass fraction) of Method II is 1.00% to 10.00%. For the overlapping part of the determination range, Method II shall be used as the arbitration method.
