GB/T 1819.7-2017 《Methods for chemical analysis of tin concentrates—Part 7:Determination of bismuth content—Flame atomic absorption spectrometric method》 Related products
This standard specifies a method for the determination of bismuth content in tin concentrates by flame atomic absorption spectroscopy (AAS), for bismuth content in the range of 0.005% to 2.50%. Absorbance measurement of bismuth in muriatic acid-nitric acid medium after sample analysis with muriatic acid and nitric acid. This standard provides a reliable method for accurate analysis of bismuth content in tin concentrates, ensuring accuracy and repeability of results.
