Abstract

The reflection coefficient method for describing volume and solute fluxes through membranes is generalized to take into account the nonideality of the solutions bathing the membrane and/or multicomponent systems. The reflection coefficient of the impermeable species in these systems is less than unity by a coefficient gamma. The reflection coefficient obtained solely from the volume flow equation, sigma(v), will always be less than the reflection coefficient obtained from the solute flow equation, sigma(8) (v). These two coefficients are related by sigma(8) (v) = sigma(v) + gamma.

摘要

用于描述通过膜的体积通量和溶质通量的反射系数方法得到推广，以考虑浸泡膜的溶液的非理想性和/或多组分体系。在这些体系中，不可渗透物质的反射系数因系数γ而小于1。仅从体积流方程得到的反射系数σ(v)，将始终小于从溶质流方程得到的反射系数σ(8)(v)。这两个系数通过σ(8)(v)=σ(v)+γ相关联。
