摘　　要：建立了适合双组分溶液吸附的固定床吸附流出曲线预测模型．测定了活性炭对苯酚和氯代苯酚双组分溶液的吸附，其吸附平衡可用扩展的Ｆｒｅｕｎｄｌｉｃｈ吸附等温式表示．采用由单组分吸附实验获得的酚传质扩散系数，理论预测了不同操作条件下的吸附流出曲线，并与实验比较，结果表明：理论预测曲线与实验曲线能很好地吻合．A predicted model for adsorption affluent curves of binary component solution was developed. The adsorption of two phenolic compounds on activated carbon made from coal was studied. Theadsorption equilibrium was described by extended Freundlich adsorption isotherm. By using the adsorption- predicted model, the theretical breakthrough curves under other operation conditions were obtained withtranfer and diffusion coefficients from single component experiment. The results showed that the theoretical breakthrough curves agreed well with those experimental ones.
