EDXRF analysis of murgul pyrite ore concentrates

Abstract Murgul pyrite ore from the city of Artvin, Turkey was analysed by means of X-ray fluorescence (XRF) by using the standard addition method. The XRF method with an 241 Am annular source of excitation and a Si(Li) detector is employed The results give useful knowledge about the concentration levels of Fe, Cu, As, Sn, Sb, In and I in Murgul pyrite ore.

Elemental composition of cement Kiln dust, raw material and cement from a coal-fired cement factory using energy dispersive X-ray fluorescence spectroscopy

Abstract Cement Kiln dust raw material, and cement samples collected from the coal-fired cement factory of Askale at Erzurum in Turkey were characterized with the standard addition method using energy-dispersive X-ray fluorescence techniques. An annular 100 mCi 241 Am radioactive source emitting 59.5 keV photon and annular 50 mCi 55 Fe radioactive source emitting 5.96 keV photon were used for excitation. Samples are prepared from powder sifted by a 300-mesh sieve. The characteristic K X-rays of the different elements were detected with a Si (Li) detector. The results are presented and discussed in this paper.

Determination of P, S, Cl, K, and Ca in Human Urinary Stones by EDXRF

Abstract Human urinary stones, taken from recurrent urinary stone ailing patients, were investigated with an energy dispersive x‐ray fluorescence (EDXRF) spectrometer. The concentrations of major elements in these stones, e.g., P, S, Cl, K, and Ca, were determined by using comparison‐standard methods. This work is a contribution for doctors, to help minimize laboratory investigations and expenses, as well as the discomfort of patients, by speeding up the research of medical etiologic problems of patients with urinary stone disease.

L-subshell and total L-shell photoeffect cross-sections measurements for Pb, Au, W, and Ta at

Abstract L-subshell and total L-shell photoeffect cross-sections were experimentally determined at 59.5 keV using energy dispersive X-ray fluorescence spectrometry for Pb, Au, W, and Ta. The obtained experimental results were compared with theoretical and available experimental values.

Determination of Ore Concentrates by Energy Dispersive X-Ray Fluorescence Spectrometry

Abstract EDXRF analysis has broad applications in the quantitative analysis of major and minor elements in geological, geochemical, and environmental studies, including the fields of sedimentology, stratigrapy, geochemistry, and mineral exploration. Evaluation of its potential for the analysis of major and minor elements in Bozalt and Dedemaksut ores were performed. Physical basis of used standard addition method, experimental set-up, the procedure of sample preparation and the results of analysis were presented. The correlation coefficients for each of elements analyzed (r greater than 0.986) were achieved.

The qualitative and quantitative analysis of Sarıkamış ore by energy dispersive X-ray fluorescence

The aim of this study was to determine the concentration of trace elements present in Sarıkamış ore by the standard addition method. The elements determined were Ca, Ti, Fe, Sr, Ba. The equipment used for this study was a Si(Li)-detector, a multichannel analyzer and 55Fe and 241Am radioisotope sources. The physical basis of the analytical method used, the procedure of sample preparation and the results are presented.
