This International Standard specifies a flame atomic absorption method for the determination of the calcium and magnesium contents of sodium hydroxide for industrial use.
The method is applicable to products having Ca and Mg contents greater than
- 2,5 mg/kg and 0,5 mg/kg respectively, if an acetylene-air flame is used;
- 0,6 mg/kg and 1,0 mg/kg respectively, if an acetylene-dinitrogen monoxide flame is used.
