1 Scope
GB/T 16484 provisions of this part of the determination of rare earth chloride, barium carbonate, the amount of light rare earth oxide.
This section applies to the rare earth carbonate light rare earth oxide of barium chloride determination. Measurement range. barium oxide 0.10% to 2.00%.
2 principle of the method
Sample with anhydrous sodium carbonate melt, the flooding, and filtered. Residue was dissolved in nitric acid, perchloric acid. In dilute nitric acid medium, directly to the argon plasma
Sub-light excitation, spectral measurement.
3 Reagents and materials
3.1
anhydrous sodium carbonate.
Nitrate 3.2 (rho1.42g/mL).
3.3
perchloric acid (rho1.67g/mL).
3.4
nitric acid (1 + 1).
3.5
HCl (1 + 1).
3.6
sodium carbonate solution (20g/L).
3.7
barium chloride solution (250g/L).
3.8
ethanol.
3.9 Barium standard solution
Weigh 1.4371g by 110 °C baking 1h and cooled to room temperature in the dryer benchmark barium carbonate, placed
100mL beaker, add 20mL water, was added dropwise hydrochloric acid (3.5) until completely dissolved, the low temperature carbon dioxide purge heated to boiling, cooled to room temperature.
Moved into 1000mL volumetric flask, dilute with water to volume, and mix. This solution 1mL containing 1000µg barium.
3.10
pairs nitrophenol indicator (1g/L).
3.11
argon ( > 99.99%).
4 Instrument
4.1
Inductively coupled plasma spectrometer with a resolution of < 0.006nm (200nm).
4.2 source
argon plasma light source.
5 Sample
5.1 Preparation of rare earth chloride sample
A sample was crushed, quickly placed in a weighing bottle immediately weighed.
5.2 Preparation of light rare earth carbonate sample
weigh the sample immediately after the opening.
Step 6 Analysis
6.1 Sample
Weigh 0.50g sample (5), accurate to 0.0001g.
