摘　　要：建立了可模拟一定相对湿度气流条件下的活性炭性能评价系统。研究湿度、CO_(2)及Xe浓度对活性炭吸附放射性气体性能影响。结果表明,一定条件下气流相对湿度升高不利于活性炭吸附放射性气体;对于放射性氪氙,随着CO_(2)浓度升高,活性炭吸附性能逐渐降低,气流中稳定性氙浓度影响可以忽略。The performance evaluation system of activated carbon was established to simulate the air flow with certain relative humidity.The effects of humidity,CO_(2)and Xe concentration on the adsorption of radioactive noble gas were studied.The results show that the increase of relative humidity is not conducive to the adsorption of activated carbon.With the increase of CO_(2)concentration,the adsorption capacity for Kr/Xe of activated carbon decreased gradually.The influence of stable xenon concentration in the gas flow can be ignored.

关 键 词：相对湿度 活性炭 放射性气体
