| 内容記述 | In the present study, we performed tracer experiments to compare the elution behaviors of Tc and Re through a TEVA resin column to measure 99Tc and Re in environmental samples. From a practical viewpoint, enriched 185Re is a good yield monitor for 99Tc and Re in water samples. The TEVA resin showed a high selectivity for Tc and Re in ca. a 0.1M HNO3 solution. When an appropriate combination of nitric acid solutions, that is, 1M and 8M, was used for washing and stripping, respectively, the elution behaviors of Tc and Re were the same. Both elements could be concentrated in 5 mL of 8M HNO3. Mo has an isotopic abundance of 24.13% at mass 98, which might interfere with the measurement of 99Tc by ICP-MS as 98MoH+, however, the resin did not sorb other matrix elements including Mo under the cited condition for nitric acid solutions. Thus, the resin was applicable to determination of Tc and Re concentrations in natural water samples by ICP-MS using enriched 185Re as a yield tracer. | |||||
