The effect of sample preparation on metal determination in soil by FAAS
Zofia Kowalewska , Ewa Bulska , Adam Hulanicki
AbstractDifferent methods for the determination of several metals in soils by flame atomic absorption spectrometry (FAAS) were investigated. Different procedures for total dissolution of soil: I - HF+HClO4, H3BO3, HCl digestion (conventional heating), II - HF+HClO4, H3BO3 digestion followed by fusion with LiBO2 (conventional heating) and III - HF+HCl+HNO3, H3BO3 digestion (microwave heating), as well as a leaching procedure with HNO3+HClO4, HCl were tested and compared. For quality assessment, the certified reference material S-1 soil was used. For most of the investigated metals, the best accuracy and precision were achieved when the procedure I or III were used. The developed procedure was applied to the analysis of soil samples from crude oil refinery and dump of petroleum origin wastes regions.
