| 摘 要： | 在测定巯基中空纤维亲和膜对Hg ^2＋动态等温吸附方程的基础上,利用C＋＋语言编程,按Langmuir、Lang- muir-Freundlich和扩展的Langmuir 3个模型对吸附Hg ^2＋实验数据进行拟合,分别检验了实验数据的拟合程度.这3个模型对实验数据都拟合较好;相对其它两个模型,扩展Langmuir模型提供了最好的拟合,从而推断出巯基中空纤维亲和膜对Hg ^2＋的动态等温吸附是非完全的单分子层吸附.

| Abstract: | On the basis of dynamic isothermal adsorption, the three models for Langmuir, Langmuir-Freundlich and Ex-pended-Langmuir are used to fit the experimental data of Hg2 + adsorbed by the hollow fiber affinity membrane modified with mercapto, and the fitting degree of the three models to the experimental data is investigated by Language C + + . The results show that the three models can fit to the experimental data. Compare with other models, the Expended-Langmuir model gives the best fitting. Then it can be inferred that the dynamic isothermal adsorption of the hollow fiber affinity membrane modified with mercapto for Hg2 + is not complete monolayer adsorption. |
