Direct Determination of Beryllium, Cadmium, Lithium, Lead and Silver in Thorium Nitrate Solution by Electrothermal Atomization Atomic Absorption Spectrometry

Direct Determination of Beryllium, Cadmium, Lithium, Lead and Silver in Thorium Nitrate Solution by Electrothermal Atomization Atomic Absorption Spectrometry

An electrothermal atomization atomic absorption spectrometric (ET-AAS) method is developed for the direct determination of Ag,Be,Cd,Li and Pb in thorium nitrate solution. The method offers detection of sub-nanogram amounts of these analytes in 100 microgram thorium samples with a precision of around...

Zusammenfassung:An electrothermal atomization atomic absorption spectrometric (ET-AAS) method is developed for the direct determination of Ag,Be,Cd,Li and Pb in thorium nitrate solution. The method offers detection of sub-nanogram amounts of these analytes in 100 microgram thorium samples with a precision of around 10%. A number of spiked samples and pre-analysed Th0 2 samples have been analysed to evaluate the performance of the analytical methods developed here.
