GB/T 6730.45-2006 Iron ores Determination of arsenic content Arseno-molybdenum blue spectrophotometric method after hydrogen arsenide separation (English Version)
Warning: Personnel using this part of GB/T 6730 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 conditions stipulated in the relevant national laws and regulations. This part of GB/T 6730 specifies the method for the determination of arsenic content by arsine hydrogen separation-arsenic molybdenum blue spectrophotometry. This section applies to natural iron ore, iron concentrate and lump ore, including the determination of arsenic content in sintered products. Measuring range (mass fraction): 0.003% to 0.50%.
