Description

This paper presents the results for the determination of eleven elements in a sample of environmental origin(IAEA SL-1) which was floated for a proficiency test exercise by IAEA for the laboratories using x-ray fluorescence technique. Analysis was performed on a wavelength dispersive x-ray fluorescence spectrometer using lithium fluoride (LiF200) and pentaerythritol (PET) crystals in combination with sealed proportional counter (Kr) for the estimation of K, Ca, Fe, Ti, Mn, Ni, Cr, Zn, Sr and Ba. Accuracy of the method for most of the elements was found within +- 5%. (author)
