Detection of Some Elements in Sand (Reddish Orange and Black) by Using X-Ray Fluorescence Device

Abstract

This research deals with one of the applications of spectroscopy, which is the detection of some components of sand and the concentrations of these elements using X-ray fluorescence technology and comparison between them. Where sand samples were taken from Bara north Kordofan region (red-orange, black) from surface and depth (30cm, 70cm). It was found that the elements present on the surface of the red-orange sample are: Silicon (Si), Zirconium (Zr), Thorium (Th), Titanium (Ti), and their concentrations respectively (18.5%- 3.1%- 4.8%- 6.2%). And at depth 30cm found the same element (Si- Zr- Th- Ti) but with a different focus and it is (8.12%- 0.2%- 5.22%- 12.4%). And black sand sample at the surface were the elements that contained it (Si- Zr- Th- Ti) and their concentrations respectively (32.3%- 3.02%- 9.25%-14.01%). At depth 70cm an iron element (Fe) was found to add to these elements (Si- Zr- Th- Ti-Fe) concentrated also respectively (2.21%- 2.26%- 7.20%- 8.45%- 7.66%).
