| Abstract: | Energy-dispersive polarized X-ray fluorescence (ED-P-XRF) spectrometry was evaluated for the analysis of low level contaminated soils for four important contaminant elements (Cr, As, Cd and Pb) and major elements (Fe, Mn, Ti, P, Ca, K, Si, Al, Mg and Na) commonly found in soils. Using a LiBO2 and Li2B4O7 fusion method, synthetic standards were prepared in Al2O3 matrices for trace elements and SiO2 matrices for major elements. Matrix corrections were based on loss-eliminated alpha coefficients and the sample analysis was carried out on an ‘as-received basis’. The method was validated using certified reference materials. Analytical figures of merit and the effect of the use of catch-weights are presented. The results of this study demonstrate that this ED-P-XRF method is suitable for the as-received analysis of contaminated soils for the determination of low parts-per-million level contaminant elements and percent level major elements. |
