| 摘 要： | 叙述了通过改变填充5A分子筛色谱柱的载气流速和色谱柱温度,改变氪、氙的保留时间,实现氪、氙分离。分离后,在低温下分别用活性炭收集。结果表明,延长氪、氙色谱柱保留时间的间隔,可提高氪、氙的去污系数;在–80oC低温下,活性炭能很好地收集氪和氙,回收率>95%。

| Abstract: | The retention time of Xe and Kr can be varied by changing the flow rate of carrier gas and temperature of the chromatography column packed with 5A molecular screen.It can be used for separating the noble gases.Test results show that an enhanced decontamination factor can be observed by extending the interval between retention times of Kr and Xe.Over 95% of the Kr and Xe can be absorbed by active carbon at –80oC. |
