The stability of the slurry was studied and it was shown that, when NH4H2PO4 modifier is added, the shape of the time resolved absorbance signal for the sample and the standards is similar and the calibration line obtained using aqueous standards is parallel to the standard addition line. Results obtained for several reference materials (lead contents between 6.1 and 64.4 μg/g) were in good agreement with the certified value, the relative standard deviation being 3-9%.
