Capabilities of the PIXE, PIGE and RBS techniques in the studies of moldavites
Havránek, Vladimír ; Mizera, Jiří ; Řanda, Zdeněk
Analytical capabilities of the PIXE, PIGE and RBS ion beam analytical techniques run in a simultaneous mode have been studied on several samples of moldavites. Combining the methods allowed determination of more than 20 major and trace elements. Determination of F and Li by PIGE is of a particular importance, as information about their content in moldavites and other tektites is mostly missing.
Determination of Sr, Ba, Rb, and Cs in biological reference materials using a radiochemical group separation procedure
Mizera, Jiří ; Řanda, Zdeněk
Strontium, barium, rubidium, and cesium in selected, predominantly biological, reference materials was determined using neutron activation analysis (NAA) in two different analytical modes - instrumental NAA with epithermal neutrons, and NAA with radiochemical group separation of Sr-Ba and Rb-Cs (RNAA). The RNAA procedure was based on decomposition of irradiated samples by alkaline-oxidative fusion followed by precipitation of Sr and Ba sulfates, and sorption of Rb and Cs onto ammonium phosphomolybdate.
Radioanalytical Methods IAA07
Vobecký, Miloslav
Proceedings "Radioanalytical Methods" present the review of the current state and new trends in activation analysis. The course is organized by the group of radioanalytical methods of the Spectroscopic Society J. M. Marci and the group of nuclear chemistry of the Czech chemical society, in cooperation with the Technical University in Prague.
