| 内容記述 | We participated in the interlaboratory comparison tests organized by the IAEA Marine Environment Laboratory in Monaco for the certification of this new reference material, analyzed the activities of 239Pu, 240Pu, 239+240Pu, 241Pu, the atom ratio of 240Pu/239Pu, and the activity ratio of 241Pu/239+240Pu by a highly sensitive isotope dilution SF-ICP-MS method combined with two-stage chromatographic separation and purification. Detailed results of Pu activity and isotope composition will be reported. With a mean chemical yield of 65 % for 242Pu tracer, we found that the experimentally established values for 239Pu, 240Pu, 241Pu and 239+240Pu activities are almost the same as those in the IAEA-381 seawater reference material. Regarding the 239+240Pu activity, we provided the most precise and accurate result among the twelve laboratories participated in the interlaboratory comparison. | |||||
