GB/T 1819.15-2017 "Methods for chemical analysis of tin concentrates, Part 15: Determination of fluorine content Ion selective electrode method" specifies the determination method of fluorine content in tin concentrates, which is suitable for the determination range of 0.010% to 3.00%. Method After melting the sample with sodiumhydrate and sodium peroxide, the concentration of fluoride ions is determined by the Ion selective electrode method. This standard provides a technical basis for the accurate determination of fluorine content in tin concentrates and is suitable for the quality control and analysis of related products.
