Simultaneous determination of trace elements in serum by energy-dispersive x-ray fluorescence spectrometry.
Energy-dispersive x-ray fluorescence is applied in the analysis of human serum to determine the concentrations of several elements simultaneously with minimal manipulation of the sample. The analytical procedure has been developed with standard sera, and standardization, detection limits, and reproducibility have been established. A 50-microL sample of diluted serum, to which an internal standa...
متن کاملEnergy Dispersive X-Ray Spectroscopy for the Determination of Trace and Main Elements
The results from various samples reported here show that energy dispersive x-ray spectroscopy is available as an efficient analytical method; one that has emerged from the qualitative and semiquantitative overview analysis phase. Particularly the ability to improve sensitivity or reduce statistical error using optimized excitation has led to an important advancement in capturing the primary sig...
متن کاملStudy of Heavy Metals and Other Elements in Macrophyte Algae Using Energy-dispersive X-ray Fluorescence
Fucus vesiculosus L. seaweeds from three estuarine stations were analysed by X-ray fluorescence, providing results for the concentration of total In order to study the differential accumulation of heavy metals by different parts of Fucus, four different structures of the algae, base, stipe reproductive organs and growing tips, were analysed. Some elements (e.g. Cu and Fe) are preferentially acc...
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 ...
