PHOTOCATALYTIC DEGRADATIO OF ORGANIC DYE BY SILVER NANOPARTICLE FROM AKCALYPHA WILKESIANA VIA GREEN ROUTE

Abstract

Silver nanoparticle (AgNP) was synthesized using a medicinal plant Acalypha wilkesiana leaf extract through bottom-up approach. synthesis of nanoparticle via green route is simple, easy to handle and inexpensive in comparison of physical and chemical methods. Phytochemical screening of Acalypha wilkesiana determines the presence of coumarins, flavonoids, sterol, tannin, phenol and saponin. Synthesis of nanoparticle were detected at regular intervals with proper characterization technique majorly include UV-Vis spectroscopy. Further characterization involves the Scanning Electron Microscopy/ Transmission Electron Microscopy (SEM/TEM) which determines the size and shape of the nanoparticle. Fourier transform infrared spectroscopy helps in finding the biochemical function group of plant extract which serves as reducing and capping agent in nanoparticle synthesis. And crystal nature of nanoparticle was analysed via X-ray diffraction (XRD). Here we aimed the remediation of polluting aqueous solution via green route of silver nanoparticle synthesis and study the photocatalytic activity of organic dyes and ability to detect the toxic metal like Pb, As, Ni, Hg, Cr, Co, Fe, Mn, Pd and Se.
