| Abstract/Summary |
The vapour generation of cadmium by the reaction with sodium tetrahydroborate (NaBH4) was performed using a continuous flow reactor. The effects of thiourea and coba1t(II) ions on the sensitivity of the determination were tested. Depressive effect of chelating compounds (EDTA) on the Cd signal was investigated. The method was applied to the determination of Cd in soil extracts and the results were compared with the results of ETAAS and FAAS. The detection limit (3σ) was 0.03 ng cm-3 and the precision for 2 ng cm-3 was up to 10 %. A certified reference material CRM 483 (BCR) was extracted and analyzed for cadmium content, the results were in good agreement with certified values.
