测定了不同温度和浓度条件下苯酚和氯代苯酚在活性炭上的吸附，采用非线性回归流出曲线的方法获得了对应于不同温度和浓度的酚的表面扩散系数。结果发现：温度升高，表面扩散系数增大；同一温度下，浓度增大，表面扩散系数增大。数据分析结果表明酚表面扩散系数与吸附温度的关系符合Arrhenius方程，而酚表面迁移活化能与浓度的关系可用经验式E=E0＋Acβ表示。
The adsorption of phenol and chlorophenol on activated carbon under different temperature and concentration was measured. The surface diffusion coefficient of phenols corresponding to different temperature and concentration was obtained by non-linear regression curve. The results show that: the surface temperature increases, the surface diffusion coefficient increases; the same temperature, the concentration increases, the surface diffusion coefficient increases. The data analysis results show that the relationship between surface diffusion coefficient and adsorption temperature accords with the Arrhenius equation. The relationship between activation energy and concentration of phenolic surface migration can be expressed by E = E0 + Acβ.
