Two types of proteins, bovine serum albumin (BSA) and bovine γ-globulin (BGG) were used in these experiments. The flux profiles of FFE process were strongly influenced by electrokinetic effects in FFE process. The electrokinetic effects were electrophoresis, electro-osmosis and electrolysis. It was observed that the migration of electrolysis products (H+) changed the pH of retentate which consequently influenced the permeate flux during the FFE process. The lowest permeate flux occurred at the isoelectric point (IEP) of both BSA (pH 4.9) and BGG (pH 5.86–6.70). It was found that the protein–membrane interactions played important role on the permeate flux profile due to electrostatic interaction/repulsion in the FFE process. 2009-08-03T08:53:00Z 2009-08-03T08:53:00Z 2009-04-20 Article Separation and Purification Technology, vol.66 (2), 2009, pages 273-278. 1383-5866 http://www.sciencedirect.com/science/journal/13835866 http://hdl.handle.net/123456789/6669 en Elsevier B.V. |
