ABSTRACT = {In this study, cellulose triacetate (CTA) based nanocomposite membranes were developed by
incorporation of carboxylic acid functionalized multiwalled carbon-nanotube (cMWCNT) and
graphene oxide (GO) which have enhancement of both flux and fouling resistance properties of
the membranes. Membranes were casted at room temperature and annealed at 90o
C hot water
for 10 minutes. The incorporation level of both the nanomaterials is 1.5% of the CTA polymer
weight in the nanocomposite membranes. Prepared membranes were characterized in terms of
water contact angle, surface morphology and mechanical strength. The performance of the
membranes was evaluated both in reverse osmosis (RO) and forward osmosis (FO) mode. The
water flux is observed to increase by ~43% in CTA-cMWCNT and ~69% in CTA-GO membranes
than the pure CTA membranes in RO mode (2000ppm NaCl feed at 1551kPa applied pressure)
but it is ~41% and ~86% in FO mode (DI water as feed & 1.0 molar NaCl as draw solution) for
CTA-cMWCNT and CTA-GO membranes respectively. Nanocomposite membranes containing
functionalized CNT & GO were found more biofouling resistant property. The flux recovery is
~62% in pure CTA membrane, whereas it is ~73% for CTA-cMWCNT and ~82% for CTA-GO
membranes.},
