This International Standard specifies a flame atomic absorption method for the determination of the calcium content of phosphoric acid for industrial use (including foodstuffs).
Determination of calcium content down to 10 mg/kg by photometric measurement of absorption of the 422.7 line emitted by a hollow cathode calcium lamp. Also for use in the food industry.
