- 論文の詳細を見る
Adsorptive membranes have been recently developed for affinity or chelating separation to reduce diffusion resistance, which is a major factor in broadening of the breakthrough or elution curve. Since the axial distance along the fluid flow is relatively short, the heterogeneity in the membrane is expected to influence the performance of the adsorption. The heterogeneities in membrane structure such as porosity, thickness and pore size are evaluated theoretically by moment analysis. The first, second and third moments are shown as a function of heterogeneity such as porosity distribution. The parameters involved in the system are adsorption equilibrium constant, Peclet number, and adsorption rate constant. The influences of these parameters as well as heterogeneity are evaluated. The heterogeneity produced unfavorable peak broadening and skewness.
