This International Standard specifies a molybdenum blue spectrophotometric method for the determination of phosphorus in aluminium ores and minerals.
The method is applicable to materials having phosphorus contents, expressed as diphosphorus pentoxide between 0,01 and 5 % (m/m).
The arsenic content of the sample does not affect the determination.
