ELEMENTAL ANALYSIS OF DIFFERENT RADISH (RAPHANUS SATIVUS L.) CULTIVARS BY USING WAVELENGTH-DISPERSIVE X-RAY FLUORESCENCE SPECTROMETRY (WDXRF)

KAYMAK, H. C.; I. GUVENC and A. GUROL, 2010. Elemental analysis of different radish (Raphanus sativus L.) Cultivars by using wavelength-dispersive X-ray fluorescence spectrometry (WDXRF). Bulg. J. Agric. Sci., 16: 769-774 The aim of this work is to study the applicability of a quantitative WDXRF (Wavelength-Dispersive X-ray Fluorescence) method, for determination of minerals in radish specimens. In this study, we have quantitatively and semi-quantitatively analysed the four different radish (Raphanus sativus L.) cultivars (cvs. 'Siyah', 'Beyaz', 'Antep' and 'Iri-Kirimizi'). We have found that major elements; namely N and K; a few minor elements; Na, Mg, P, S, and Ca, and a lot of trace elements; Mn, Fe, Cu, Zn, Al, Ti, Cr, Br, Rb, Sr, Sn, Ba and La. The obtained trace element concentrations range from 0.01 to 3.24 mg per 100 g. This rapid method has been found to be a reliable technique for analyzing the mineral content in radish. At the end of this work, it was clearly said that Wavelength-dispersive X-ray fluorescence spectrometry (WDXRF) could be used for the analysis of mineral contents of radish and other vegetables.
