Abstract |
In this work, cellulose acetate-based flat sheet membranes were fabricated using PEG 400
and glycerol as an additive in various composition of doped solutions. The fabricated
membranes were characterized using SEM, AFM, and FTIR analysis techniques. According
to SEM, it was observed that the addition of PEG 400 wt% resulted in the formation of
membranes with micro and nanopores and the distribution of pores was not uniform. To
avoid heterogeneity in pore sizes, glycerol was added in the dope solution containing CA
and PEG 400 (6.2 wt%). The addition of 10.1 wt% glycerol resulted in the formation of
membrane with uniform distribution of pores. The permeation study of synthesized
membranes was carried out using pure water, urea, and glucose solution which revealed
that CA PEG-10.1 wt% glycerol-blended membrane (M8) is most sugar selective and
selectivity up to 15.21 is documented.
