| 摘 要： | 本文先研究了两种煤质活性炭对不同浓度苯酚酚和对氯代苯酚单组分溶液的吸附，应用固定床吸附动力学模型，非线性回归固定床吸附流出曲线数据，获得了酚类在活性炭上的扩散传质系数。结果发现，酚类的表面扩散系数ＤＳ强烈地依赖于入口酚的浓度，随着酚浓度的升高，表面扩散系增大。

| Abstract: | The adsorption of two phenolic compounds on activated carbon made from coal was studied. By using adsorption dynamic model of fixed-bed, the surface diffusion coefficients of phenols were obtained by regression the data of effluent curves. It was shown that the surface diffusion coefficient was input concentration-dependent. It increased with the increasing of input concentration. The competitive adsorption of phenolic compound on activated carbon was also carried out. It indicated that phenol was weakly-adsorbed species while p-chlorophenol was strongly-adsorbed. |
