GB/T 6150.2-2022 Methods for chemical analysis of tungsten concentrates—Part 2:Determination of tin content—Potassium iodate titrimetry and inductively coupled plasma atomic emission spectrometry
Abstract
This document specifies the methods for determining the tin content in tungsten concentrate, including the potassium iodate titration method (Method I) and inductively coupled plasma atomic emission spectrometry (Method II).
This document is applicable to the determination of tin content in tungsten concentrate. The determination range (mass fraction) of Method I is 1.00% to 20.00%. The determination range (mass fraction) of Method II is 0.010% to 2.00%. For the overlapping part of the determination range, Method II shall be used as the arbitration method.
