dc.abstract.enThis work refers to a comparative study of sorbents widely used in determinations of 99Tc such as TEVA resin and Dowex 1. Despite having a similar functional group of quaternary amines, both materials represent different chromatographic methods—extraction (TEVA resin) and anion exchange (Dowex 1)—which provides a diverse range of their properties significant in determination of 99Tc in flow conditions. The comparative tests, carried out in a SIA-LOV (Sequential Injection Analysis—Lab-on-Valve) system combined with mass spectrometric (ICP-MS) detection, considered several factors that are crucial from the standpoint of resin´s utility such as sorption capacity, durability, or selectivity, critical in 99Tc separation from interferences. The developed and optimized analytical procedure based on the application of the TEVA resin provided determinations of 99Tc at minimum detectable limit (MDL) 6.00 mBq L-1 in 50 min and has been successfully employed in analyses of samples from nuclear industrial and research units (reactor coolant and sewage) as well as from the river surrounding the nuclear reactor. The method proved to be sufficient for routine analysis of water samples in accordance with EPA standards. The reliability of the method was confirmed in the analysis of the BH standard provided by the NPL for inter-laboratory proficiency tests. The 99Tc recovery for all real samples was evaluated as 80–100%.
