Laboratory use specifications and test methods GB/T 6682 Analysis
Principle 3
Sample hydrofluoric acid, sulfuric acid decomposition, adding a certain amount of potassium as deionization agent, 1% sulfuric acid medium, atomic absorption spectrophotometry
Acetylene flame measured absorbance or rubidium oxide emission intensity, calculated the amount of rubidium oxide - on the meter, at a wavelength of 780.0nm, the use of air.
4 Reagents
Unless otherwise indicated in the analysis are consistent with the use of analytical reagents and GB/T 6682 water analytical laboratory.
4.1 Hydrofluoric acid (ρ1.13g/mL). WARNING. Hydrofluoric acid is toxic and corrosive, the operation should wear gloves to prevent skin contact
4.2 sulfate (11). Warning. When diluted improper operation could easily cause burns
4.3 potassium chloride solution ρ (K2O) = 30mg/mL. Weigh 47.49g potassium chloride (KCl) in a beaker, dissolved in water and transferred to 1000mL
Volumetric flask, dilute to the mark, shake.
Rubidium oxide 4.4 Standard solution.
a) rubidium oxide standard stock solution. Weigh 0.6469g spectroscopically pure rubidium chloride (105 ℃ bake 2h and placed in the dryer to cool to room
Temperature) in 250mL beaker, add water, dissolved and transferred to 500mL volumetric flask, dilute to the mark, shake. This solution oxygen
Rubidium concentration of 1.0mg/mL;
b) rubidium oxide standard solution. Pipette 25.00mL rubidium oxide standard stock solution [4.4a)], set 500mL flask with water
Dilute to the mark. Rubidium oxide concentration of the solution was 50.00μg/mL.
5 Instruments
5.1 atomic absorption spectrophotometer (with transmitter function). Attached rubidium element hollow cathode lamp.
5.2 Analytical balance. three, a sense of the amount of 0.1mg.
6 Sample
6.1 Sample particle size less than 74μm.
