GB/T 8704.9-2009 《Ferrovanadium - Determination of manganese content - The potassium periodate oxidation photometric method and flame atomic absorption spectrometric method》 Related products

This standard applies to the determination of manganese content in ferrovanadium and specifies specific methods for determination using potassium periodate spectrophotometry and flame atomic absorption spectroscopy (AAS). The potassium periodate spectrophotometry is suitable for the determination of manganese content between 0.05% and 0.60%, while the flame atomic absorption spectroscopy (AAS) method is suitable for the determination of manganese content between 0.10% and 1.00%. The standard details the determination principle, reagent preparation, operation steps and calculation methods, providing a standardized process for the accurate determination of manganese content in ferrovanadium.
