GB/T 1819.13-2017 《Methods for chemical analysis of tin concentrates—Part 13: Determination of magnesium oxide content,calcium oxide content—Flame atomic absorption spectrometric method》 Related products

This standard specifies the determination method of oxidation mg and oxidation calcium content in tin concentrate, which is applicable to the analysis of oxidation mg content in the range of 0.010% to 3.50% and oxidation calcium content in the range of 0.050% to 15.00%. Samples are analyzed by muriatic acid, nitric acid, hydrofluoric acid and perchloric acid, and the Absorbance of oxidation mg and oxidation calcium is determined by flame atomic absorption spectroscopy (AAS). This standard provides an accurate detection method and is an important reference for the analysis of tin concentrate composition.
