Quantitative Analysis by Energy Dispersive X-ray Fluorescence by the Transmission Method Applied to Geological Samples
Three certified samples of different matrices (Soil-5, SL-1/IAEA and SARM-4/SABS) were quantitatively analysed by energy dispersive X-ray fluorescence with radioisotopic excitation. The observed errors were about 10-20% for the majority of the elements and less than 10% for Fe and Zn in the Soil-5, Mn in SL-1, and Ti, Fe and Zn in SARM-4 samples. Annular radioactive sources of Fe-55 and Cd-109 ...
متن کاملDetermination of multi-element profiles of street dust using energy dispersive X-ray fluorescence (EDXRF).
Street dust samples have been collected in different areas in Hong Kong associated with various levels of traffic and pedestrian flow, and the concentrations of 23 chemical elements have been determined using energy dispersive X-ray fluorescence (EDXRF). The 23 studied elements were Na, Al, Si, Cl, Ti, Ba, V, Cr, Mn, Fe, Co, K, Ca, Ni, Cu, Zn, As, Pb, Rb, Sr, Y, Zr and Sn. A profile for average...
متن کاملDetermination of multi-element profiles of soil using energy dispersive X-ray fluorescence (EDXRF).
The source profile for soil in Hong Kong is important both for determination of the main air pollutant source in Hong Kong and for assessment of the impact of Asian dust storms on Hong Kong. Soil associated with different rock types have been sampled, and the concentrations of 19 chemical elements, Na, Al, Si, Ti, V, Cr, Mn, Fe, Co, K, Ca, Ni, Cu, Zn, Pb, Rb, Sr, Y and Zr, have been determined ...
متن کاملAnalysis of the elemental concentrations in rat femur's head using energy dispersive X ray fluorescence spectrometry
EDXRF spectrometry is used normally to determine the concentration of the different elements in a sample with advantages of good sensitivity, multielemental capabilities, fast, non-destructive and because of this simple relation to the fundamental physics of atom-radiation interaction, make of EDXRF a highly attractive analytical technique. A major goal for research in biomedical sciences over ...
متن کاملDendrochemical patterns of calcium, zinc, and potassium related to internal factors detected by energy dispersive X-ray fluorescence (EDXRF).
Energy dispersive X-ray fluorescence (EDXRF) provides highly sensitive and precise spatial resolution of cation content in individual annual growth rings in trees. The sensitivity and precision have prompted successful applications to forensic dendrochemistry and the timing of environmental releases of contaminants. These applications have highlighted the need to distinguish dendrochemical effe...
