This International Standard specifies an atomic absorption spectrometric method, after extraction, for the determination of the phosphorus content of natural and artificial cryolite and of aluminium fluoride for industrial use.
The method is applicable to products having phosphorus contents, expressed as P2O5, in the range 5 to 60 mg/kg.
