Scope

This standard specifies the method for the determination of carbonate content in sodium hydroxide for industrial use. This standard is applicable to products whose mass fraction of carbonate (calculated as Na₂CO₃) is greater than or equal to 0.02%. Through preliminary experiments, the samples can be divided into three categories: 1.1 Sodium hydroxide without sulfide and chlorate. 1.2 Sodium hydroxide containing sulfides. This standard applies to products with a mass fraction of sulfide (calculated as Na₂S) less than 0.1%. 1.3 Sodium hydroxide containing chlorate. This standard applies to products with a mass fraction of chlorate (calculated as Na₂ClO₃) less than 0.2%. For 1.2 and 1.3, the analytical procedure needs to be modified appropriately due to the presence of special components (see details given in Chapter 10).
