从理论上建立了一个膜理论/离子耦合模型，该模型结合了高回收率扩散控制膜系统的浓差极化/反扩散和离子耦合现象，并用于预测多溶质膜系统的渗透水质。浓度极化因子（Y）被建模为操作压力和采收率的函数。发现多溶质系统中的单个溶质传质系数（MTC）是给水成分的函数，并使用单溶质和双溶质实验获得的溶质MTC确定。

A film theory/ion coupling model combining both concentration polarization/back diffusion and ion coupling phenomena for high recovery diffusion-controlled membrane systems was theoretically developed and used to predict permeate water quality for multi-solute membrane systems. The concentration polarization factor (Y) was modeled as functions of operating pressure and recovery. The individual solute mass transfer coefficients (MTCs) in multi-solute systems were found to be a function of feed water composition and were determined using solute MTCs obtained from single- and bi-solute experiments.
