Tracking the phase behavior of light hydrolyzed and oxidized cellulose acetate membrane #
Asymmetric cellulose acetate (CA) membrane are widely produced by phase inversion method. By a change in the molecular structure of CA polymer; it will act differently while quenching medium drowned in non-solvent bath. A light hydrolysis also oxidation and combination of those subjected to CA powder to claim morphological behavior on the prepared membrane. An FT-IR spectra affirmed deacetylation of CA polymer. Produced membranes are pictured by SEM cross-sectional images to show high porosity after chemical process. Also membranes are prepared to treat Dye/Water solution. Within this section by an ultrafiltration process at 3bar un-like raw CA membrane, chemically modified ones have much more permeation flux (up to 100 L/m2.h) but dye rejection was decreased as a coincident.
