用理想吸附溶液（IAS）模型预测了四氯化碳、三氯乙烯和四氯乙烯在活性炭和碳质树脂上的多组分吸附平衡。进行了单溶质吸附实验以获得等温线参数，并进行了多组分吸附实验以验证IAS模型的结果。该模型描述了浓度范围为1的多组分吸附平衡- 每升2000微克。然而，也有一些明显的例外，不容易用实验误差来解释，这表明IAS模型在总体上可能无效。与活性炭相比，含碳树脂对三种挥发性有机化合物（VOCs）中的每一种都具有更高的吸附能力，并且竞争时的吸附能力顺序与根据吸附等温线确定的每种VOCs的相对吸附能力预期的顺序一致，即从高到低（四氯乙烯、三氯乙烯和四氯化碳）。 包括14个参考文献、表格和图表。

The ideal adsorbed solution (IAS) model was used to predict multicomponent adsorption equilibria for carbon tetrachloride, trichloroethylene, and tetrachloroethylene in two-component and three-component solutions on activated carbon and carbonaceous resin. Single-solute adsorption experiments were performed to acquire isotherm parameters and multicomponent adsorption experiments to verify IAS model results. The model described some of the multicomponent adsorption equilibria for the concentration range of 1-2000 micrograms per liter. However, there were notable exceptions not easily explained by experimental error, suggesting that the IAS model may not be valid in general. Carbonaceous resin has a higher capacity for each of the three volatile organic chemicals (VOCs) than does activated carbon, and the order of adsorbability when in competition agrees with that expected from the relative adsorbability of each VOC as determined from its adsorption isotherms, i.e., from high to low (tetrachloroethylene, trichloroethylene, and carbon tetrachloride).
