| 内容記述 | An analytical method for 239Pu and 240Pu in marine sediment samples which uses quadrupole ICP-MS was developed in this work. A simple anion-exchange chromatography system was employed for the separation and purification of Pu from the sample matrix. A sufficient decontamination factor of 14000 for U, which interferes with the determination of 239Pu, was achieved. High sensitivity for Pu determination was obtained, which led to an extremely low concentration detection limit of ca. 8 fg/ml (0.019 mBq/ml for 239Pu; 0.071 mBq/ml for 240Pu) in a sample solution or an absolute detection limit of 42 fg in 5 ml sample solution by using the shield torch technique. Analytical results of 239+240Pu and 240Pu/239Pu ratio in IAEA 368 (ocean sediment) reference material indicated that the accuracy of the method was satisfactory. The developed method was successfully applied to a study on Pu behavior in the sediments from Sagami Bay, Japan. The observed high 240Pu/239Pu ratio in the sediment core indicated that there was additional Pu input derived from close-in fallout in addition to the global fallout. | |||||
