Severe drinking water shortage is a significant problem worldwide and now becoming a
crucial issue in the field of water purification. The main key of this work is to enhance
membrane performance permeability, rejection, anti-fouling and antibacterial activity.
This study seeks to discover the influenced of biosynthesis of Zinc Oxide (ZnO)
nanoparticles by using fruits extracts of Ananas Comosus towards the characteristic,
properties and performance polysulfone (PSf) mixed matrix membrane. The biosynthesis
ZnO, (ZnO (P)) nanoparticles powder was successfully synthesized by using fruit extracts
of Ananas Comosus. The characterization and performance of the ZnO (P) were conducted
in this study and compared with commercial ZnO, (ZnO (C)). In the beginning, the purity
and crystallinity of the ZnO (P) powder was determined by using X-ray diffraction
analysis (XRD) that showed the optimum synthesized composition peak was matched well
with the ZnO (C) with crystallite size in the range of 12.2nm. The bandgap energy value
of the ZnO (C) and ZnO (P) was 2.20 eV and 3.17 eV respectively which in line with the
photocatalytic activity as many as 66.4% and 96.2% for ZnO (C) and ZnO (P) respectively
in this study. The inhibition area of ZnO (P) nanoparticles powder is also relatively larger
than ZnO (C) nanoparticles powder. All seven samples were successfully prepared via the
phase inversion method. Obviously, the addition of ZnO nanoparticles in the PSf
membrane has increased the membrane hydrophilicity property that strongly affected the
membrane characteristic, property and performance. The hydrophilicity of the 3% ZnO
(P) as compared to 0% ZnO and ZnO (C) increased up to 34.21% and 23.92% respectively
which in line with the improvement of membrane morphology, surface roughness thus
further enhanced the performance in term of permeability of the membrane. SEM results
displayed that the addition of ZnO nanoparticles had enhanced the membrane porosity,
reduced the tensile strength, increased in surface roughness as the additives increased up
to 3% ZnO (P) which leads to enhance the antibacterial properties of the membrane.
Membrane permeability was increased to 140.79% in 3% ZnO (P) compared to 0% ZnO.
The antibacterial activity of the membrane with ZnO nanoparticle was improved
especially with the presence of biosynthesis ZnO in 5% ZnO (P). The result also showed
that the green reduction agent of ZnO had exceedingly affected the membrane
characterisation and its performance. In conclusion, the addition of ZnO has increased the
performance of the PSf membrane especially with the green synthesis reduction agent of
Ananas Comosus in 3% ZnO (P). |
