Scope

WARNING - Personnel using this section should have practical experience in formal laboratory work. This section does not address all possible security issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the relevant national regulations. This part of GB/T 4333 specifies the determination of aluminum content in ferrosilicon by chrome azure S spectrophotometry, EDTA titration and flame atomic absorption spectrometry. This section applies to the determination of aluminum content in ferrosilicon. Chrome azure S spectrophotometry range (mass fraction): 0.10% to 0.60%; EDTA titration method (mass fraction): 0.60% to 5.00%; flame atomic absorption spectrometry range (mass fraction): 0.05% ~5.00%
