ActiveSodium hydroxide for industrial use - Determination of calcium and magnesium content - Complexometric method
工业用氢氧化钠 钙镁总含量的测定 络合滴定法
Application Summary AI generated
This standard specifies a complexometric titration method for determining the combined calcium and magnesium content in sodium hydroxide used for industrial applications. It is applied in chemical manufacturing and quality control laboratories to ensure the purity of caustic soda, particularly for processes where these metal impurities could affect downstream reactions or product quality. The method is relevant for testing raw materials in industries such as soap and detergent production, water treatment, and alumina refining.
