Abstract 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 Th02 samples have been analysed to evaluate the performance of the analytical methods developed here.
