Resumo
In this work, an analytical procedure for the quantitative analysis of the metals determination in
house dust samples by wavelength dispersive x-ray fluorescence technique (WDXRF) is described. The
fundamental parameters method (FP) was applied and direct pressed powder technique was used for
sample preparation.
The methodology validation and measurement uncertainty were evaluated by the
EURACHEM/CITAC Guide 4715-92, statistical tests. Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe,
Ni, Cu, Zn, As, Se, Sr and Pb were determined in the standard reference materials.. The SRM data
presented an uncertainty of measurement, calculated as the relative standard deviation (RSD), lower
than 3% for all the elements at 0.05% significance level; except for Na, K, Ti, Ni, Se e Pb
determination. These elements presented 10.9 - 3.4 – 5.4 – 5.7 – 5.0 -3.8 % RSD values, respectively.
The accuracy of the method presented the Z-score values between -2
