为了寻找合适的吸附剂去除核后处理厂尾气中的放射性惰性气体（85 Kr），进行了吸附剂筛选试验。在195和273 K下考察了不同吸附剂对Kr的吸附性能。研究了氮气载气对Kr吸附的影响。发现一些碳基吸附剂Ambersorb 572、Ryujyo-Sirasagi G2 x4/6-3和Molsievon X2 M4/6具有大的吸附容量。以天然丝光沸石为原料，经离子交换制备的H型丝光沸石吸附剂对Kr具有良好的吸附性能，其吸附效果与活性炭相当。
A screening test of adsorbents was carried out in order to find out suitable adsorbents for the the removal of a radioactive noble gas (85Kr) in the off-gas of nuclear reprocessing plants. The adsorption performances of various adsorbents for Kr were investigated at 195 and 273 K. The effect of nitrogen carrier gas on the adsorption of Kr was examined as well. Some carbon-based adsorbents—Ambersorb 572, Ryujyo-Sirasagi G2x4/6-3 and Molsievon X2M4/6—were found to have large adsorption capacities. The H-mordenite adsorbent fabricated from a natural mordenite by ion-exchange with the HC1 solution was found to have a good adsorption performance for Kr, which is almost comparable to that of the activated charcoal.
