| Abstract: | This study presents preparation of cellulose acetate
(CA) and aminated polyethersulfone (APES) blend ultrafilrtation
membranes by precipitation phase inversion technique in
various polymer blend compositions in the presence / absence of PEG
600. Prepared membranes were used for rejection of
proteins (bovine serum albumin, egg albumin, pepsin, and trypsin). Toxic
heavy metal ions [Cu(II), Zn(II), and Cd(II)] from
dilute aqueous solutions were subjected to separation by blend membranes. On
increasing APES concentrations, rejection of proteins
and metal ions decreases, whereas permeate flux has an increasing trend.
Extent of proteins separation was found to be directly
proportional to molecular weight of protein. CA / APES blend ultrafilration
membranes demonstrated better
performance compared to the membranes prepared from pure cellulose acetate. |
