Studies of Trace Elements in Some Varieties of Rice (Oryzasativa) by Energy Dispersive X-ray Fluorescence Technique.

Abstract

Applicability of Energy Dispersive X-ray Fluorescence
(EDXRF) technique for trace elements in some varieties of rice
(Oryza sativa) from different fields of the region was demonstrated.
The work being presented here includes trace element analysis of
some rice varieties.  Concentration of metals K, Ca, Mn, Mg, Fe,
AI, Ti, P, Na, Zn, Cu, and Si in rice from eastern Vidarbha zone
are studied. All the samples were analysed without any chemical
treatment. To investigate any possible contamination in the grinding
procedure or loss of some elements due to the drying process a few
samples were analysed by total reflection X -ray fluorescence technique.
The effects of chemical fertilizers, perticides and Ilerbicides
on the elemental concentration of rice grain were also investigated
by this technique.
