SYNTHESIS OF COPPER NANOPARTICLES USING BIO METHOD IN CASSIA AURICULATA LEAVES EXTRACTAbstract
Knowing the morphology of Copper nanoparticles was confirmed by Field Emission Scanning Electron microscopy (FE-SEM). Herein, we are reporting a novel biological approach for the formation of copper nanoparticles using leave. Copper sulfate was made to reduce with an aqueous solution of Cassia auriculata leave extracts. X-Ray diffraction (XRD) pattern reveals the formation of Copper nanoparticles, which shows crystallinity. Field emission scanning electron microscopy (FE-SEM) suggested particles size and spherical shape in the range of 38.1-43.5 nm. UV absorption studies of copper nanoparticles showed that have absorbance in the range 488.5 to 514.3 nm and FT-IR studies of copper nanoparticles were showed that the stretching frequency of fingerprint region at 509.21 cm-1 for Cu-O bond.
