| dc.description | 99Tc isotope is a beta emitter of great concern because of its long half-life (2.1*105 y). It is considered one of the most mobile
radionuclides in nature easily incorporated into the trophic chain, exposing humans to its beta radiation and its increasing
abundance. During the last decades large amounts of this radionuclide have been released into the environment from
anthropogenic sources such as nuclear industry and medical applications. Thus, 99Tc determination is needed in order to establish
an environmental control. Therefore, we have developed a novel and miniaturized LOV system, allowing 99Tc determination in
environmental samples (see figure). We propose a fast method that uses TEVA resin and ICP-MS. The developed system allows
reduction of reagents volume (e.g. 6 mL HNO3 6.5 mol L-1 as eluent), the minimization of sample handling, improving the
reproducibility and the sample throughput and attaining a significant decrease of both time and cost per analysis. | |
