Spectrometry determination of elements content
1 Scope
This section provides aluminum fluoride, fluorine, aluminum, sodium, silicon, iron, sulfur, phosphorus content (F, Al, Na, SiO2, Fe2O3, SO2-4, P2O5 represented)
Measurement method.
This section applies to fluorine, aluminum, sodium, silicon, iron, sulfur, aluminum fluoride determination of phosphorus content. Determination of the range in Table 1.
Table 1
Component measuring range /%
F 50.00 ~ 68.00
Al 25.00 ~ 36.00
Na 0.020 ~ 10.00
SiO2 0.010 ~ 0.60
Component measuring range /%
Fe2O3 0.010 ~ 0.50
SO2-4 0.10 ~ 2.00
P2O5 0.0020 ~ 0.30
2 principle of the method
Sample anhydrous lithium tetraborate and lithium metaborate mixed flux melted, add a small amount of lithium bromide (or iodide) as a release agent. In the melt prototype
Melted into glass samples. Measured by X-ray fluorescence spectrometer. Theoretical coefficient α or fundamental parameter calibration between the absorbent element -
Enhancement.
3 Reagents
3.1 anhydrous lithium tetraborate and lithium metaborate mixed flux [Li2B4O7 (67%) + LiBO2 (33%)]. at 700 ℃ burning 2h, dry place
Dryer saved.
3.2 remover. a saturated solution of lithium bromide or ammonium iodide solution (300g/L).
3.3 Sample Monitoring. Monitor sample should be stable glass, contains all the elements of calibration, so that its content should be less than the statistical error count rate
Or equal to the count rate calibration element statistical error.
4 Instrument
Platinum 4.1 - gold alloy crucible (95% Pt + 5% Au).
4.2 platinum - gold alloy casting (95% Pt + 5% Au). bottom mold material thickness of about 1mm, making it difficult to deformation.
Note. The sample vessel melt casting mold can be combined. If the sample in the crucible directly after melt molding, the bottom surface of the inner wall of the crucible is required smooth.
4.3 fusion machine. automatic flame melt melting prototype prototype or high-frequency inductors, if other types of prototype melting temperature not lower than 1100 ℃, and can be controlled
Temperature, temperature control accuracy of ± 15 ℃.
4.4 wavelength dispersive X-ray fluorescence spectrometer. end window rhodium anode X-ray tube.
5 Sample
The specimen shall conform YS/T 581.11 in 3.3 requirements.
