3 Method summary
Mixing the sample with nitric acid to dissolve the salt. Perchloric acid, phosphoric acid, manganese oxide by Potassium seven purple high price of manganese, in
Spectrophotometer at a wavelength of 530nm absorbance measurement to calculate the amount of manganese.
4 Reagents
Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity of its water.
4.1 Hydrofluoric acid (ρ = 1.15g/mL).
4.2 nitric acid (ρ = 1.42g/mL).
4.3 hydrochloric acid (ρ = 1.19g/mL).
4.4 phosphoric acid - perchloric acid mixture (31). three phosphoric acid (ρ = 1.69g/mL) and a perchloric acid (ρ = 1.67g/mL) and mix.
4.5 high potassium iodate solution (5%). Weigh 5.00g potassium periodate, placed in 250mL beaker, add 60mL water, 20mL of nitric acid (4.2),
After warming to dissolve, cooled, diluted with water to 100mL, and mix.
4.6 sodium nitrite solution (1%).
4.7 manganese standard solution.
4.7.1 Manganese standard stock solution (500μg/mL). Weigh 0.5000g manganese (wMn≥99.9%) (to be pre-placed manganese sulfate
(595) cleaning, until the surface of the manganese oxide washed out, immediately washed repeatedly with distilled water, and then placed in anhydrous ethanol washed 4 to 5 times,
Out on a dryer and dried before use), placed in 250mL beaker, add 10mL water, 10mL of nitric acid (4.2), dissolved by heating,
Boil drive to make nitrogen oxides, remove the cooled to room temperature and transferred to 1000mL volumetric flask, dilute with water to volume, and mix.
4.7.2 manganese standard solution (100μg/mL). Pipette 20.00mL manganese standard solution (4.7.1) in 100mL flask, add 1mL nitrate
Acid (4.2), dilute to the mark and mix.
4.8 without reducing water species. deionized water (or distilled water) heated to boiling, with 10mL per liter of sulfuric acid (13) and acidified, not fresh high
Iodate, continue to boil for a few minutes, after cooling use.
