【摘要】 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。更多还原

【Abstract】 In order to study the adsorption characteristics of activated carbon fiber, a new analytic solution for batch adsorption with a linear isothermal is obtained. Experiments were carried out for the adsorption of chloroform on activated carbon fiber in a batch tank. With the adsorption equilibrium constant determined from a separate experiment, the particle -fluid mass transfer coefficient and the effective diffusivity were evaluated by the error map for the analytic solution.更多还原
