Scope
This part of GB/T 6730 specifies the determination of arsenic content by distillation separation and arsenic-molybdenum blue spectrophotometry. This part is applicable to the determination of arsenic content in natural iron ores, iron concentrates, and pellets, including sintered products. The determination range (mass fraction) is 0.0001% to 0.1%.
