Radioisotope X-ray fluorescence analysis of some elements in colemanite ore

The standard addition method for the determination of As, Sr, In, Sn, Sb, I, Cs and Ba elements in colemanite ore of Bigadiç region in the city of Balikesir (Turkey) was applied by using an Energy Dispersive X-ray Fluorescence (EDXRF) system. Samples are prepared from powder sifted by a 300-mesh sieve. An annular 100 mCi 241Am radioactive source emitting 59.5 keV photons was used for excitation. The characteristic K X-rays of the different elements were detected with a Si(Li) detector. These results are presented and discussed in this paper.
