In this work, we report about cellulose acetate nanofiltration (NF) membrane preparation according to the phase inversion process. Pore size was monitored by using dope solutions of two polymer concentrations (20 and 22 wt-%) and annealing temperatures from 60–80°C. Membrane characterization include

Surface modification of nanofiltration cellulose acetate (CA) membranes was carried out by alternating layer-bylayer deposition of acidic chitosan (CHI) and sodium alginate (ALG) as the cationic and anionic polyelectrolyte, respectively. The supporting CA membranes were obtained by a phase separatio

Asymmetric cellulose diacetate (CA) based membranes were prepared according to the phase inversion process from acetone/formamide (2:1 wt./wt.) casting solutions. The polymer concentration was varied from 15 to 25 wt.% in order to produce membranes with pore size distributions ranging from low molec
