X-ray fluorescence spectrometry
1 Scope
This standard specifies the method for determination of aluminum electrolytic with a dry impermeable feed nutrient contents.
This standard applies to aluminum electrolysis dry impermeable compound of aluminum, silicon, iron, titanium, potassium, sodium, calcium and magnesium (oxides expressed as Al2O3, SiO2,
Fe2O3, TiO2, K2O, Na2O, CaO, MgO) measurement. Determination of the range in Table 1.
Table 1
Component content range /% range component content /%
Al2O3 10.00 ~ 50.00 SiO2 10.00 ~ 60.00
Fe2O3 0.010 ~ 10.00 TiO2 0.010 ~ 5.00
K2O 0.010 ~ 5.00 Na2O 0.010 ~ 5.00
CaO 0.010 ~ 5.00 MgO 0.010 ~ 5.00
2 principle of the method
Sample was mixed with molten flux anhydrous lithium tetraborate and lithium metaborate to eliminate mineralogical effects and particle effects, and cast for X-ray
Fluorescence spectrometer to measure the shape of the glass, glass measuring X-ray fluorescence intensity in the measured elements. According to the calibration curve or equation to points
Analysis, calibration equation established with reference materials and inter-element interference effect correction. Matrix effect theoretical α coefficient or fundamental parameter method
Absorption correction between elements - enhancing effect.
Note. Due to the versatility of molten glass technology allows the use of a variety of flux and calibration mode. But it should meet certain reproducibility, sensitivity, and accuracy. If the
A laboratory own method complies with the terms of, you can considered to meet this standard.
3 Reagents
3.1 anhydrous lithium tetraborate and lithium metaborate mixed flux [Li2B4O7 (12) LiBO2 (22)], the flux contains a certain amount of water, the following should be adopted
One of two methods to compensate.
a) burning 2h at 700 ℃, cooling backup in the dryer;
B) When the flux per kg sufficiently mixed Take two parts, a predetermined melting temperature of the molten 10min, another predetermined melt
Room melted, take the loss on ignition greater flux correction amount, according to equation (1) to calculate a correction factor. Flux should be sealed. Weekly or every
Determination of loss on ignition kg once.
F =
100-L
(1)
Where.
F --- the correction factor;
L --- Loss on ignition, expressed as a percentage.
3.2 the ammonium nitrate solution. 500g/L.
