纳滤膜传质过程的研究

Research on the Mass Transfer Mechanism of Nanofiltration

作为一种新型膜分离技术,描述纳滤膜传质过程的数学模型有:不可逆热力学模型、电荷模型、细孔模型以及道南-立体细孔模型和静电位阻模型等。针对这些典型数学模型的建立和应用发展情况进行了重点介绍。并在此基础上,讨论了各种溶质对纳滤膜传质过程的影响。

As a new membrane separation technology,the mass transfer process of nanofiltration（NF） membranes can be explained with some models,such as the non-equilibrium thermo dynamic model,the charge model,the pore model,the Donnan-steric hindrance-pore model,the electrostatic and steric-hindrance model and so on.The establishing,application and development of those typical models were chiefly introduced.On this basis,the influences of various solutes on nanofiltration membrane mass transfer process were discussed.
