✦ Synopsis

Polycarbonate foils with thicknesses from 0.08 to 2.5 mm containing Ti, Cr, Fe and Ba were analysed by energy-dispersive x-ray fluorescence (EDXRF) spectrometry. Neutron activation analysis (NAA) was used to validate the EDXRF results. The element concentrations ranged for Ti from 0.04 to 0.75%, for Cr from 0.03 to 0.3% and for Fe from 0.25 to 1.30%. The concentration of Ba was about 1%. The results obtained by EDXRF were of the same quality as those provided by NAA, but the NAA method was found to be more accurate for polycarbonate samples containing both Ti and Ba.

For textile detergency studies, a method was developed for the determination of iron on cloths by wavelengthdispersive x-ray fluorescence (WDXRF) spectrometry. Iron was measured directly on the cloths without prior sample pre-treatment. A linear calibration line was obtained for cloths with iron con

Trace elemental analyses of rubies and sapphires from different countries of origin were carried out by the EDXRF technique. It was found that K, Ti, Cr, Fe, Cu, Zn, Sr and Ba are generally present in natural rubies and Cr, Ni, Cu and Zr in synthetic ruby. The synthetic ruby shows a clean spectrum d
