Scope
This part of GB/T 6730 specifies the determination of phosphorus content by the molybdenum blue spectrophotometric method. This method is suitable for the determination of phosphorus content in natural iron ores, iron concentrates, and pellets, including sintered products. The presence of arsenic, barium, and titanium does not affect the determination results. The determination range (mass fraction) is 0.003% to 2.00%.
