1 Scope
GB/T 16484 provisions of this part of the determination of earth chloride and light rare earth carbonate, nickel oxide content.
This section applies to rare earth, light rare earth carbonate - Determination of the amount of nickel oxide chlorination. Measurement range 0.0020% to 0.010%.
2 principle of the method
Sample with nitric acid dissolved in dilute nitric acid medium with air - acetylene flame, using the standard addition method in the atomic absorption spectrometer wavelength
Nickel absorbance measured at 232.0nm, the calculation of the amount of nickel oxide in the sample.
3 Reagents
Nitrate 3.1 (rho1.42g/mL).
3.2
Hydrogen peroxide (30%).
3.3
nitric acid (1 + 1).
3.4 Nickel standard stock solution
Weigh 0.2500g of nickel [w1 (Ni) >=99.99%] in 250mL beaker, add 10mL of nitric acid (3.3), heated until completely dissolved, removed, cooled to room temperature, transferred to 250mL volumetric flask, dilute to the mark with water and mix. This solution
1mL containing 1mg nickel.
3.5 Nickel standard solution
Pipette 10.00mL Nickel standard stock solution (3.4) in 1000mL flask, add 50mL of nitric acid (3.1),
Diluted with water to volume, and mix. This solution 1mL containing 10µg nickel.
4 Instrument
Atomic absorption spectrometer, with a nickel hollow cathode lamp.
Under optimum conditions the instrument, those who can reach the following indicators can be used.
--- Characteristic concentration. in the measurement sample solution matrix consistent solution, characteristic concentration of nickel is not more than 0.080µg/mL.
--- Precision. measuring the absorbance of the standard solution 10 times the highest concentration, the absorbance of the standard deviation does not exceed an average of 1.0%; most
Low concentrations of the standard solution (not a zero standard solution) absorbance measured 10 times, and the standard deviation should not exceed the maximum average absorption solution
0.5% luminosity.
--- Linear curve. The curve is divided into five sections according to concentration, absorbance difference between the absorbance difference between the highest and the lowest segment of the segment
Ratio of not less than 0.7.
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 2.50g sample (5), accurate to 0.0001g.
