Methods for Chemical Analysis of Iron, Steel and Alloy - The Sodium (Potassium) Periodate Photometric Method for the Determination of Manganese Content
1 Method Summary
After the dissolution of the sample by acid, in the medium of the sulfuric acid and phosphoric acid, the manganese is oxidized into septivalency with sodium periodate (kalium) and then measure its absorbance.
2 Reagent
2.1 Hydrofluoric acid (ρ 1.15g/ml).
2.2 Hydrochloric acid (ρ 1.19g/ml).
2.3 Nitric acid (ρ 1.42g/ml).
2.4 Nitric acid(1+4).
2.5 Nitric acid(2+98).
2.6 Sulfuric acid (1+1).
