RESUMO
The work was based on the identification and determination of selected elements in teas, plants and medicinal products for the treatment of anemia. To evaluate the quality of medicinal plants Urtica dioica L., Papaver somniferum, L., leguminous plant Lens culinaris, M. and also in medicaments Aktiferrin® gtt., Ferronat® retard pot.tbl and Sorbifer® Durulues® por. Tbl. Flm. was used nuclear analytical method Radionuclide X-ray Fluorescence Spectrometry. This method is suitable for the analysis of samples in the solid state and a liquid state. Solid samples were homogenized and compressed into tablets of defined shape and weight. Liquid samples were filtered through a chelating membrane 3M EmporeTM, which are used to selectively capture the polyvalent metal cations and are preconcentrating the elements from sample. Samples were analysed using radiation radionuclide 238 Pu and evaluated by means of a semiconductor detector and a multichannel analyser.
