  • Title: Mechanistic approach to membrane mass transport processes (mini review).
    Author: Kargol M.
    Journal: Cell Mol Biol Lett; 2002; 7(4):983-93. PubMed ID: 12511967.
    Abstract:
    Since the physical interpretation of practical Kedem-Katchalsky equations is not clear, we consider an alternative, mechanistic approach to membrane transport generated by osmotic and hydraulic pressure. We study a porous membrane with randomly distributed pore sizes (radii). We postulate that the reflection coefficient (sigma(p)) of a single pore may equal 1 or 0 only. From this postulate we derive new (mechanistic) transport equations. Their advantage is in clear physical interpretation.
