    Abstract: In order to enrich radioactive xenon in the atmosphere high-efficiently, the authors researched the method for separating and purifying xenon by utilizing preparative chromatography technology and adsorption materials performance difference. The parameters of separation and purification system were determined after the research results were analyzed. The performance of the xenon separation and purification system was validated, the system of the whole flow is less than one hour, the xenon sample recovery is the better than 90%, and the purity is better than 95%. The xenon sample can meet the requirements of radioactivity measurement.
    Key words: Xe; separation; purification; chromatography technology
