为研究活性炭纤维的吸附性能,针对纤维状吸附剂,建立了间歇吸附模型并推导出当吸附等温方程为线性时该模型的解析解。用活性炭纤维吸附水中微量三氯甲烷实验对模型进行了验证。实验测定了间歇吸附器内水中微量三氯甲烷的主体浓度变化曲线及吸附等温平衡线,通过比较主体浓度变化曲线与模型计算值,由误差等值图法估算了有效扩散系数以及液膜传质系数。 In order to study the adsorption properties of activated carbon fibers, a batch adsorption model was established for the fibrous adsorbent and an analytical solution of the model was derived when the adsorption isotherm equation is linear. The model was verified by using activated carbon fiber to adsorb trichloromethane in water. The main concentration curve and adsorption isotherm equilibrium curve of trichloromethane in water in batch adsorber were determined experimentally. By comparing the curves of body concentration and calculated values ​​of the model, the effective diffusion coefficient and the mass transfer coefficient.
