MINERAL CONTENT OF NATIVE VEGETABLES OBTAINED BY ENERGY DISPERSIVE XRAY FLUORESCENCE SPECTROMETRY
Journal Title: Journal of Science And Arts - Year 2008, Vol 9, Issue 2
Abstract
In this work the non-destructive methodology based on Energy Dispersive Xray fluorescence (EDXRF) has been applied for the determination of some major and minor elements (K, Ca, Fe, Mn, Cu, Zn) in different vegetation species: [i]Atriplex hortensis, Rumex patientia, Lactuca sativa, Spinacea oleracea [/i]. From data obtained about the mineral content of analyzed samples it could be concluded that all of these plants can be use in supplementary mode as a very high nutritional foodstuffs. The EDXRF measurements were made using the Elvax spectrometer having an X-ray tube with Rh anode and a solid state Si-pin-diode X-ray detector with a 140 μm Be window and 200eV at 5.9 KeV (Fe55 line) energy resolution.
