本文介绍了马尾藻在间歇式和固定床柱系统中对锰的生物吸附实验数据。批平衡数据用于Langmuir和Freundlich等温线的非线性拟合。采用基于流体和吸附剂质量平衡的数学模型来表示实验固定床柱数据。突破模型中使用的等温线参数与实验室数据有很大的不匹配。另外，增加的固定床柱数据为等温线评价提供了新的参数，相应的突破曲线模拟剖面与实验结果吻合较好
This paper presents experimental data of the biosorption of manganese onto Sargassum filipendula in both batch and fixed-bed column systems. Batch equilibrium data were used for nonlinear fittings of the Langmuir and Freundlich isotherms. A mathematical model based on mass balances in the fluid and in the sorbent was applied to represent the experimental fixed-bed column data. The utilization of isotherm parameters from the batch experiments in the breakthrough model implied a significant mismatch in relation to the laboratory data. Alternatively, additional fixed-bed column data provided new parameters for the isotherm evaluation, and the corresponding simulated profile of the breakthrough curve reached better agreement to the experimental results
