Charcoal adsorption beds are commonly used to remove radioactive noble gases from contaminated gas streams. The design of such beds requires the adsorption coefficient for the noble gas. Here an extension of the Dubinin-Radushkevich theory of adsorption is developed to correlate the effects of temperature, pressure, concentration, and carrier gas on the adsorption coefficients of krypton, xenon, and argon on activated carbon. This model is validated with previously published adsorption measurements. It accurately predicts the equilibrium adsorption coefficient at any temperature and pressure if the potential energies of adsorption, the micropore volume, and the van der Waals constants of the gases are known.
活性炭吸附床通常用于从受污染的气流中去除放射性惰性气体。这种吸附床的设计需要惰性气体的吸附系数。在此，我们对杜比宁-拉杜什凯维奇吸附理论进行了扩展，以关联温度、压力、浓度和载气对氪、氙和氩在活性炭上吸附系数的影响。该模型通过先前发表的吸附测量结果进行了验证。如果已知吸附势能、微孔体积和气体的范德华常数，它就能准确预测任何温度和压力下的平衡吸附系数。
