模拟预测空间站冷凝水通过活性炭填充柱的吸附效果

摘要在空间站冷凝水净化过程中,通过测定冷凝水模型的实际穿透曲线以及单组分有机物的吸附等温线,可以建立相应的吸附模型,活性炭吸附冷凝水中的单组分有机物满足Langmuir模型和Freundlich模型。通过进一步探究得知,活性炭对冷凝水中的苯甲醇和已内酰胺具有出色的吸附性能,对其他有机物吸附性能较弱,冷凝水模型的不同有机物之间存在较强的竞争吸附,多组分吸附等温线符合IAS-Freundlich模型和IAS-Langmuir 模型,改变苯甲醇和己内酰胺在冷凝水中的初始浓度,发现己内酰胺对于2种模型的适应能力较强。

Abstract： In the process of condensate water purification in the space station, the corresponding adsorption model can be established by measuring the actual penetration curve of the condensate water model and the adsorption isotherm of one-component organic matter. The adsorption of organic matter in the condensed water by activated carbon meets the Langmuir model and Freundlich model. Through further investigation, it is known that activated carbon has excellent adsorption performance for benzyl alcohol and caprolactam in condensed water, but weak adsorption performance for other organic matter. There is strong competitive adsorption between different organic matter in condensed water model, and the multi-component adsorption isotherm is consistent with IAS-Freundlich model and IAS-Langmuir model. By changing the initial concentration of benzyl alcohol and caprolactam in condensed water, it can be concluded that caprolactam has strong adaptability to the established models.
