Abstract:

The X-ray fluorescence spectrometry and the MA.BM.006 reference spectrophotometric methods were used to determine the content of SiO2 (%) in bauxites from different deposits. The treatment of samples prior to the analysis involved the following steps: annealing, melting using the borax method,  and the formation of beads. Certified reference bauxite samples were used for the calibration curve. The calibration curve was produced with the correlation coefficient of r =0.9999 and the standard error of  S = 0.0246. The average residual value between the content of SiO2 determined using the XRF method, and the reference method was 0.045, with a standard deviation of 0.068. The XRF method was statistically verified by the F- and t- tests (using the standard sample and the reference method). The values obtained in the tests show that the XRF method yields accurate results and that there are no standard errors.

Investigation and Measurement of Ash Content of Coal in Zirab Coal Mine-Iran Using Dual Energy -Ray and X-Ray Fluorescence Methods

Coal with low ash content has an important role in the coal and steel industry. There are different methods to measure the ash content. The conventional method which is used in most coal mines of Iran, is to burn the coal and measure the remaining ash. A new method has been recently developed at Nuclear Research Center (NRC) of Iran, Which works on the basis of the absorption of the dual en...

X-ray fluorescence and potentiometry compared for determining iodine content of thyroid glands.

We compare results for iodine quantitation by x-ray fluorescence of excised thyroid glands with results of the quantitation by means of an original, newly developed chemical method, a Schöniger combustion technique, in which iodie is quantitated potentiometrically. Subsequently, we establish the accuracy and clinical suitability of the former technique in quantifying the intrathyroidal iodine.

Assessing the Environment with X-ray Fluorescence Spectrometry

In this paper we will introduce the general benefits of X-Ray Fluorescence spectrometry (XRF) for assessing the condition of the outer environment, especially where ambient aerosol particles are causing environmental disturbances. Examples from recent environmental studies are presented, and energy dispersive XRF is concluded to be a powerful, nondestructive yet easily applicable tool to supply...
