pollutants produced from pharmaceutical, textiles, papers, plastics, cosmetics
etc. are namely as dyes and other organic components in aqueous form is an
unprecedented problem in the present world. As reported while dye process,
45-90% of dyes are ousted as waste into water. Discharge of such effluents
contaminates the water-bodies which is one of the major reasons for water
scarcity. Dyes, being an organic pollutant, possess hazardous impact on aquatic
animals; aquatic plants and thereby affects mankind. With the rapid development
in the industries and growth in population, afore stated issue seems to become
an important matter of concern. Throughout the world, replenishment and
betterment of the water quality is becoming a stringent issue. Therefore, there
is an upsurge need in proper studies on the purification, separation and
reusability of such waste-water filled with dyes and lessens naturally
occurring fresh-water resource scarcity.

preferentially play a crucial role of separation process in various industries.
These membranes may be made up of inorganic (ceramic) or organic (polymer)
moiety. In the current scenario, polymeric membranes are more preferred due to
the better pore formation within the surface, flexile nature and cost effective
when compared to the former one. They have a wide range of applications. Although,
inorganic membranes are much more defiant to intense pH, oxidation, chemical
attack, possesses high mechanical strength and high durability yet it has several
disadvantages. They are not used extensively owing to the high costs and poor pore
size distribution. In addition, the membrane layer is very dense in contrast to
the mean pore size, which results in the reduction of flow rate. The blending
of organic-inorganic polymer gives rise to an upcoming research field which has
immense application in the commercial purification process.

synthesis of nanoparticles is the limelight in modern nanotechnology.
Biosynthesis of nanoparticles from plant extracts is currently under
exploitation. The high surface area to volume ratio makes nanomaterials highly
desirable for use as potential catalysts. Palladium proves to be the most
efficient metals in catalysis. Palladium has been heavily studied in a wide
range of catalytic applications including hydrogenations, oxidation,
carbon-carbon bond formation and electrochemical reactions in fuel cells.

of the most widely used polymers in membrane science is polysulfone due to its mechanical,
structural and chemical stability. There
are some investigations on introducing nanoparticles into the PSf membranes in
order to enhance the properties such as permeability, selectivity, thermal and
solvent resistant and also mechanical properties compared to neat PSf
membranes. Among the nanoparticles, metals besides improving membrane
properties can be effective catalysts because of their relatively large percentage
of their surface atoms.

Herein, we have proposed a strategy for the development of a nanoparticle
composite membrane which will be applicable for dye purification. Pd(0)
nanoparticles were synthesized from PdCl2 using resveratrol  as the reducing agent which have been
extracted earlier from plant species. Apparently, the synthesized nanoparticles
were incorporated in polymeric matrix in the form of a flat sheet membrane and
were characterized by a variety of physicochemical analytical techniques. The
membrane performance was verified by conducting permeation experiments on the
aqueous solution of the commercial dye-Crystal Violet. Permeation results were
analyzed by considering different parameters. The work done provides an insight
on selectivity and permeability of membrane and its effectiveness in dye
