GB/T 3260.3-2013 《Methods for chemical analysis of tin―Part 3：Determination of bismuth content KI photometric method and flame atomic absorption spectrometric method》 Related products

This standard specifies the determination method of bismuth content in tin, including potassium iodide Spectrophotometric method, spectra-trophotometry and flame atomic absorption spectroscopy (AAS) two measurement methods. The measurement range is 0.00050% to 0.200% and 0.00030% to 0.200%, respectively. After acid dissolving of the sample, the spectrophotometric or flame atomic absorption spectroscopy (AAS) method is used to quantify bismuth. This standard provides an accurate detection method for the analysis of trace bismuth in tin materials, which is helpful for quality control and material research.
