| 摘 要： | 比较了活性炭纤维间歇系统当吸附等温方程为Ｌａｎｇｍｕｉｒ型时表面扩散模型与孔扩散模型，获得了两模型扩散系数可相互转换的条件，分析了用间歇吸附实验研究溶质在活性炭纤维内扩散机理的可行性，同时给出当吸附等温方程为矩型时两模型的解析解。通过实验验证了部分结论。

| Abstract: | By comparing the surface diffusion model with the pore diffusion model in batch adsorption of activated carbon fiber with Langmuir isotherm, we gave the relationships between the surface diffusivity and the pore diffusivity, and analysed if one can use the batch adsorption system to research the mechanism of diffusion . In the case of rectangular isotherm, the analytical solutions were given. A part of conclusions were verified by experimental data. |
