摘要
主要介绍了几种不同吸附剂对氙气吸附性能的研究,阐述其优缺点,分析了研究现状和未来可能的发展方向。当前氙的取样分析系统应用最广泛的吸附剂是活性炭,但这些设备都出现了不同程度的长期稳定性不够的问题,不能满足禁核试条约组织筹备委员会的要求,而且活性炭有孔径分布范围较广的局限性,并不是最理想的氙吸附剂。近年来国内对活性炭纤维的氙吸附性能做了大量研究,但是由于其装填密度较小等缘故仍不能作为理想的吸附剂。其它吸附剂研究尚处于初级阶段,因此寻找和开发高效的吸附剂十分必要。
The application and development of several kinds of adsorbents on adsorption of xenon are summa- rized, and their advantages and disadvantages are analyzed, finally the development tendencies of the adsorbents are al so discussed. The current xenon detection systems mostly use activated carbon as adsorbent. But these devices have appeared to be unstable, and canlt meet the Comprehensive Nuclear Test-Ban Treatys requirement. The activated car- bon has a wider range of pore size distribution, and thus is not the best xenon adsorbent. Adsorbability toward xenon of activated carbon fibre has gain considerable attentions in China recently, but itrs still not the ideal adsorbent for its small loading density. Other adsorbentsrresearch on adsorption of xenon is still in the primary stage, thus seeking and developing efficient xenon absorbents is necessary.
