Laboratory use specifications and test methods GB/T 6682 Analysis
GB/T 14506.1 Silicate rocks - Part 1. Determination of water adsorption
3 potassium periodate photometric method
3.1 Principle
After separation of the silica filtrate with sulfuric smoke rush to make chlorine ions, organic compounds with nitric acid damage; or said sample with sulfuric acid, hydrofluoric acid, nitric
Acid treatment. A 5% to 10% sulfuric acid solution, heightening the potassium iodate oxidation of divalent manganese purple permanganate, on a spectrophotometer,
Measured at a wavelength of 525nm absorbance, calculate the amount of manganese oxide.
The reaction is. 2Mn2 5IO4- 3H2O → 2MnO4- 5IO3- 6H
3.2 Reagents
Unless otherwise stated in this section are consistent with the use of analytical reagent and GB/T 6682 analytical laboratory use in the analysis.
3.2.1 High potassium iodate.
3.2.2 ethanol.
3.2.3 hydrofluoric acid (ρ1.15g/mL). Warning --- toxic and corrosive hydrofluoric acid, the operation should wear gloves to prevent skin contact.
3.2.4 nitrate (ρ1.42g/mL).
3.2.5 sulfuric acid (11). Warning --- improper dilution risk prone
3.2.6 sulfuric acid (595).
3.2.7 phosphoric acid (11).
3.2.8 Preparation of standard solution of manganese oxide.
a) manganese oxide standard stock solution (1.0000mg/mL).
Weigh 0.7745g advance by dilute sulfuric acid (3.2.6) and then treated with ethanol (3.2.2) washed, dried high purity manganese metal after placed
Beaker, 100mL added sulfuric acid (3.2.6), dissolved by heating, cooled and transferred to 1000mL volumetric flask, dilute to the mark with water,
Shake;
