Methods for chemical analysis of nickel laterite ore
Part 19. aluminum, chromium, iron, magnesium, manganese, nickel and silicon content
Determination of energy dispersive X-ray fluorescence spectrometry
1 Scope
YS/T 820 This part sets out with an energy dispersive X-ray fluorescence spectrometry laterite nickel ore in aluminum, chromium, iron, magnesium, manganese, nickel and
The method of silicon content.
This section applies to the determination of nickel laterite ore in aluminum, chromium, iron, magnesium, manganese, nickel and silicon content, measuring range in Table 1.
NOTE. laterite aluminum, chromium, iron, magnesium, manganese, nickel and silicon content of nickel may also be employed a method in Appendix A were measured.
Table 1 elements and measurement range
Element measurement range /%
Al 0.20 ~ 5.00
Cr 0.10 ~ 2.50
Fe 5.00 ~ 55.00
Mg 0.50 ~ 15.00
Mn 0.10 ~ 1.00
Ni 0.10 ~ 3.00
Si 2.00 ~ 20.00
2 Method summary
The powder sample was prepared as a tablet or a glass fuse, on the X-ray beam emitted by the source, using the measurement sample analysis device is activated
When the fluorescent X-ray intensity produced by fat, calculated by a calibration curve of the analyte content.
3 Interference
3.1 When nickel laterite sample elements emit X-rays, generated when the spectral interference, the detector can not correctly detect the analyte emission
X-rays resulting spectra superimposed, resulting spectral interferences. The device according to the manufacturer's operating instructions to calibrate the instrument, thereby eliminating
interference.
Change 3.2 allows content elements in the sample matrix changes directly affect the X-ray absorption, thereby changing the measurements of each element
fruit. This interference usually occurs in X-ray fluorescence analysis, but not spectral interference.
3.3 Some instruments equipped with noise reduction software, can automatically check and reduce interference.
4 instruments and equipment
4.1 energy dispersive X-ray fluorescence spectrum analyzer. no energy can be used for this test method and meet the following criteria dispersive X-ray fluorescence
