【摘要】 从环境监测角度,叙述了开展活性炭对氪富集条件研究的重要意义。以氪在活性炭上的动态吸附实验为基础,研究了活性炭、温度、气体线流速和氪的分压对氪富集的影响,利用吸附材料的微结构,通过吸附理论模型拟合实验数据,得到CF-1450活性炭在191K下对氪的饱和吸附量为32.9mL/g。更多还原

【Abstract】 In order to monitor radioactive krypton distribution in the environment,active charcoal is used to enrich krypton before the sample can be submitted to further laboratory analysis.The importance and method of krypton enrichment were presented.The absorption behavior of krypton by charcoal was analyzed.The experimental setup was designed to investigate effects of working temperature,linear velocities,partial-pressure of krypton on the enrichment of krypton by charcoal.The micro-structure parameters of the absorbing material to characterize its absorbing property was used,and the experimental data with theoretical analysis to conclude that for CF-1450 was fitted.The saturation absorption capacity at 191 K is 32.9 mL/g.更多还原
