AbolishedDetermination of ammonium hydrogen carbonate for industrial use - Part 3: Sulphide content - Visible turbidimetric method
工业用碳酸氢铵的测定方法 第3部分：硫化物含量 目视比浊法
Application Summary AI generated
This standard specifies a visible turbidimetric method for determining sulphide content in ammonium hydrogen carbonate used for industrial applications. It is applied in quality control laboratories within the chemical manufacturing industry to ensure the purity of ammonium hydrogen carbonate, particularly for uses in fertilizers, food additives, or pharmaceutical intermediates where sulphide impurities must be limited. The method relies on visual comparison of turbidity against standard solutions, making it suitable for routine testing in production environments without specialized instrumentation.
