The sublimatographic separation of volatile beta-diketone, pivoloyltrifluoroacetone (PTA), chelates of fission products was studied. When Zr carrier was added, the sublimated radioactive chelates deposited on only one zone at the position of 45-60 cm (85-50 degrees C) from the position of the sample. The position agreed with the deposited position of inactive chelates of Zr. The nuclide presented in the zone was almost 95Zr. On the other hand, when Y or Eu carrier was added, the sublimated radioactive chelates deposited on two zones at the position of 20-40 cm(150-120 degrees C) and 60-75 cm (50-25 degrees C), respectively. The zone at higher temperature side agreed with the deposited position of inactive chelates of each carrier and the nuclei presented in this zone were mainly lanthanide elements (141Ce, 144Ce, 147Nd, 140La. 103Ru, 95Zr). The zone at lower temperature side was mainly carrier-free state of 95Zr, but the position of carrier-free 95Zr shifted to lower temperature side than the deposited position of inactive chelates of Zr carrier.
研究了裂变产物的挥发性β-二酮、新戊酰三氟丙酮（PTA）螯合物的升华分离。加入锆载体时，升华的放射性螯合物仅沉积在距样品位置45 - 60厘米（85 - 50摄氏度）处的一个区域。该位置与锆的非活性螯合物的沉积位置一致。该区域中呈现的核素几乎是95Zr。另一方面，加入钇或铕载体时，升华的放射性螯合物分别沉积在20 - 40厘米（150 - 120摄氏度）和60 - 75厘米（50 - 25摄氏度）处的两个区域。较高温度一侧的区域与每种载体的非活性螯合物的沉积位置一致，该区域中呈现的核主要是镧系元素（141Ce、144Ce、147Nd、140La、103Ru、95Zr）。较低温度一侧的区域主要是95Zr的无载体状态，但无载体95Zr的位置比锆载体的非活性螯合物的沉积位置向较低温度一侧偏移。
