| 摘 要： | 采用HNO3-HF-HClO4混合酸溶液分解样品。以^242Pu为稀释剂，用阴离子交换法分离纯化超痕量钚后，用铼带碳化处理技术制样，最后用同位素稀释质谱法测量样品中超痕量钚。结果表明，用该法可以对环境中10^13g级的微量钚进行定量分析。 |

| Abstract: | Environmental samples are dissolved in a concentrated HNO_3-HF-HClO_4 mixture. After addition of an appropriate quantity of a standard ~(242)Pu solution, each sample solution is purified by an anionic exchange resin column. The spiked samples are then fabricated into measuring specimens by rhenium filament carbonization technique and analyzed by isotope-dilution mass spectrometry (IDMS). The measurement results show that the procedure described in the present paper for analysis of plutonium by IDMS in environmental samples is feasible. |
