A new method has been developed aimed at determining traces of lanthanides in the materials of biological origin by NAA. The chemical procedure that involves both, selective and quantitative pre-irradiation isolation of the elements of interest and post-irradiation separation of lanthanides into two groups has been employed. The method is based on classical column ion-exchange and extraction chromatography. In the pre-irradiation step all the accompanying elements are eliminated and the quantitatively isolated lanthanides fraction is free from highly activating macro components, as well as from other trace elements, including uranium, which is the source of spectral and nuclear interferences. After neutron irradiation, the lanthanide fraction is divided into two sub-fractions, taking advantage of the different anion-exchange affinities of individual lanthanide complexes with EDTA towards strongly basic anion-exchanger. This provides the favorable gamma-ray spectrometric measurement conditions enabling reliable determination of 13 elements.
