The two models used to describe the mechanism of permeation are illustrated in Figure 2.1. One is the solution-diffusion model, in which permeants dissolve in the membrane material and then diffuse through the membrane down a concentration gradient. The permeants are separated because of the differences in the solubilities of the materials in the membrane and the differences in the rates at which the materials diffuse through the membrane The other model is the pore-flow model, in which permeants are transported by pressure-driven convective flow through tiny pores. Separation occurs because one of the permeants is excluded (filtered) from some of the po ...
