GREEN SYNTHESIS OF SILVER NANOPARTICLES USING SPINACIA OLERACEA LEAVE EXTRACT AND THEIR PHYSICAL VERIFICATION

Abstract

Silver (Ag) nanoparticles synthesized from the eco-friendly green method plays pivotal role for its use in many versatile applications. The green chemistry approach has been successfully adopted to fabricate silver nanoparticles with an average diameter of 10 nm in size from the spinach (Spinacia oleracea) leave extract. The effect of heating in the synthesis process was checked for any change in the size of the silver nanoparticles, which is not pronounced much. Characterization of four samples of silver nanoparticles with different concentrations of the salt and the extract was achieved through UV-VIS, EDX and SEM measurements.
