| Abstract/Summary |
Three atomic spectrometry methods (FAAS, ETAAS, ICP-AES) for the determination of heavy elements (Cd, Cr, Ni, Pb, V) in soils, soil extracts, plants, and biota were evaluated and compared. The precision and accuracy of spectrometric measurements were checked by certified reference materials. The ETAAS is more suitable for the determination of the elements studied in environmental samples, primarily with respect to convenient determination limits than FAAS and ICP-AES. In this work the following metrological data for ETAAS were obtained: the precision (RSD) values were in the range from 5 % to 10.3 % for Cd; from 6.7 % to 13.3 % for Cr; frown 5.4 % to 14.1 % for Ni; from 4.4 % to 14.7 % for Pb, and from 8.5 % to 18.6 % for V; the detection limits - LOD (3σblank criterion) for Cd were in the range 0.8-1.3 µg kg-1; for Cr 1.8-2.3 µg kg-1; for Pb 3.0-5.7 µg kg-1; for Ni 4.2.-5.9 µg kg-1; and for V 16.3-23.5 µg kg-1. The contents of elements obtained by the tested methods are in good agreement with the certified values of all used certified reference materials.
