| 内容記述 | Understanding of rhenium (Re) behavior in seawater gives an idea of the possible behavior of technetium-99 (99Tc), which is an important radionuclide in long-term dose assessment for humans. In this study, Re determinations in manganese nodules, which have high Mn content, were carried out. Since Mn, Tc and Re are the member of group 7A in the periodic table, accumulation of Tc and Re in the nodules was also expected. After alkaline fusions and chemical separations, Re concentrations in manganese nodules were measured by ICP-MS. Total chemical recovery of the method for Re was 95% and the detection limit was 4.5 ng/kg. Re concentrations in the manganese nodules were very low, <4.5 - 49 ng/kg. The results indicated that the nodules had been mineralized under oxic conditions. This type of nodule could not be an important geochemical reservoir of Re and 99Tc in the sea. | |||||
