Computer simulation of dynamic isothermal adsorption of hollow fiber affinity membrane modified with mercapto for Hg~(2 +)

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.
