摘　　要：采用制备色谱技术并结合吸附材料性能的差异的方法,对不同温度下4A MS柱、5A MS柱、碳黑小球(601)柱、活性碳柱的性能进行了测定,根据测定结果确定了氙分离纯化流程的设计参数及实验参数。在设计的氙分离纯化流程的基础上,通过模拟实验测得该流程获得氙样品的产额好于90%,获得氙样品的纯度好于98%,样品能满足放射性测量的要求。The performances of 4A molecular sieves column,5A molecular sieves column,carbon black pellets column,and activated carbon column in separation of xeron and the concurrent gaseous impurities were investigated at different temperature.Based on the mea-surement results,a preparative chromatographic procedure for separation and purification of Xe from air samples was established,and the technical parameters were ascertained.The procedure was tested with simulated trace Xe-containing samples.The results show that the purity of thus isolated Xe is higher than 98%,and its overall recovery is better than 90%,indicating samples prepared by this procedure can meet the requirement of the radioactive Xe measurement.
