- Scope
- This standard specifies the determination of calcium oxide and magnesium oxide by complexometric titration and the determination of magnesium oxide by atomic absorption spectrometry. This standard applies to the determination of calcium oxide and magnesium oxide in limestone and dolomite, and also applies to the determination of calcium oxide and magnesium oxide in metallurgical lime. The first part is complexometric titration, the measurement range: the amount of calcium oxide is greater than 25%, and the amount of magnesium oxide is greater than 2.5%; the second part is atomic absorption spectrometry, the measurement range is: the amount of magnesium oxide is 0.10% to 0.50%.
