Journal ArticleDOI
Thermodynamic analysis of the permeability of biological membranes to non-electrolytes
Ora Kedem,Aharon Katchalsky +1 more
TL;DR: The equations derived here have been applied to various permeability measurements found in the literature, such as the penetration of heavy water into animal cells, permeability of blood vessels, threshold concentration of plasmolysis and relaxation experiments with artificial membranes.
Journal ArticleDOI
Thermodynamics of hyperfiltration (reverse osmosis): criteria for efficient membranes
K.S. Spiegler,Ora Kedem +1 more
TL;DR: In this paper, a theory of hyperfiltration based on non-equilibrium thermodynamics is presented, in which authors combine elements of their own previous work with important contributions of other investigators.
Journal ArticleDOI
Surface characterization by FTIR-ATR spectroscopy of polyethersulfone membranes-unmodified, modified and protein fouled
TL;DR: In this article, a modified polyethersulfone (PES) ultrafiltration membrane was characterized by FTIR-ATR spectroscopy to detect chemical changes during modification.
Journal ArticleDOI
Surface modification of commercial composite polyamide reverse osmosis membranes
TL;DR: Radical grafting of two monomers, methacrylic acid and polyethylene glycolmethacrylate, onto commercial composite polyamide reverse osmosis membranes was performed and found that the membranes were surface modified without damage to their transport properties.
