Determination of interaction forces and average pore size and pore size distribution and their effects on fouling of ultrafiltration membranes

Abstract

In this paper the method of determining the interaction forces working between macromolecular solutes and the membrane material by the liquid chromatography method and the method of specifying the average pore size and the pore size distribution of membranes by use of the transport equations based on the surface force-pore flow model are illustrated. The effects of interaction forces and pore structure on ultrafiltration membrane performance, and membrane fouling, are Illustrated with data on separations of proteins in aqueous solutions as examples.
