- Scope
- This standard specifies the determination of the mass fraction of trace sulfur in fertilizer catalysts using sodium hypophosphite reduction of methylene blue spectrophotometry and barium sulfate weighing analysis. This standard is applicable to the determination of the mass fraction of trace sulfur in various types of fertilizer catalysts. The sodium hypophosphite reduction methylene blue light photometry method is applicable to the determination of sulfur with a mass fraction of 0.0005% to 0.1%. The barium sulfate weighing analysis method Suitable for the determination of sulfur with a mass fraction of 0.03% to 0.7%.
