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.
