| 摘 要： | 采用双钯柱自置换色谱法建立了1套氘浓缩实验装置。研究并讨论了该装置对氘的富集效果。实验结果表明：氘丰度为2.0%和5.0%的样品经富集后，最大氘丰度分别达到31.6%和67.3%。该装置结构简单、操作方便，适宜对低氘丰度的氢同位素气体进行有效富集。

| Abstract: | A self-displacement gas chromatography (SDGC) system using two columns packed with Pd was fabricated for deuterium enrichment. The deuterium enrichment performance of the fabricated SDGC system was investigated and discussed. The experimental results show that the maximum deuterium concentration of effluent gas is up to 31.6% from 2.0% of the sample gas, and 67.3% from 5.0% for SDGC system. The structure of the system is simple and it can be applied to deuterium enrichment from hydrogen isotopes of low deuterium concentration. |
