The primary absorption line at 228.802 nm has been used for the determination of cadmium, and an adjacent secondary line, at 228.726 nm, for iron. Fourteen bean samples and 10 soil samples from nine states all over Brazil have been analyzed. The limits of detection (3 σ, n = 10) were 2.0 μg kg-1 for Cd and 4.5 mg kg-1 for Fe. The relative standard deviation ranged from 4 to 7% for Cd and from 5 to 28% for Fe, which is usually acceptable for a screening method. The accuracy of the method has been confirmed by the analysis of two certified reference materials; the results were in agreement with the certified values at a 95% confidence interval.Submitted by Bruna Lessa (lessbruna@gmail.com) on 2012-06-19T14:08:40Z No. of bitstreams: 1 (79)jf9024773.pdf: 775124 bytes, checksum: dfcb882e52271812c1392bd86cf48d1c (MD5)Made available in DSpace on 2012-06-19T14:08:40Z (GMT).
