Wavelength dispersive X-ray fluorescence spectrometry (WD-XRF) has been applied to the direct determination of hazardous elements in solid polyethylene (PE) materials. A series of six in-house PE reference materials was prepared by compounding some additives in to the basic resin. Determination of the elemental concentrations and the homogeneity of the elemental distribution for the references was analyzed by INAA. Emphasis was placed on the analytical performance in the analysis of the PE materials by WD-XRF. Satisfactory results and a good agreement were obtained for three elements (As, Cd and Hg). Calibration graphs of a very good linearity obtained by XRF for the three elements are presented. Finally, the performance of the technique in terms of a precision (0.1-6.6%) and accuracy (0.2-1.9%) was investigated.
