Using several asymmetric cellulose acetate membranes (CA), transport parameters such as the hydrodynamic (%p) and osmotic (Β£~) permeability and the asymptotic solute rejection (r) were determined from hyperfiltration experiments at 29C with different brine solutions (0.i M and 0.5 M NaCI, 0.i M NAN0
## Abstract Cellulose acetate (CA) is highly comparable to other synthetic polymer materials and is effective in the hemodialysis process. In this work, asymmetric CA membranes were synthesized with the phaseβinversion method. CA with a molecular weight of 52,000, poly(ethylene glycol) (PEG) with a
Using models of dead-end filtration theory, the kinetics of forming dynamic layers of sulfate lignin (SL) and sodium carboxymethylcellulose ( Na-CMC) onto CA membranes during cross-flow filtration of dilute solutions of polymers was studied. It was found for both polymers (compact SL and linear Na-C
