Synthesis of silver nanoparticles using Satsuma mandarin (Citrus unshiu) peel extract: A novel approach towards waste utilization

摘要

Silver nanoparticles (AgNPs) were synthesized using Satsuma mandarin (Citrus unshiu) peel extract without adding external surfactant and capping agent. Aqueous silver (Ag~+) ions when exposed to Satsuma mandarin peel extract were reduced and formed silver nanoparticles in the size range 5-20 nrn. The AgNPs produced were characterized by UV-visible, X-ray diffraction (XRD), transmission electron microscopy (TEM), and by energy dispersive X-ray analysis (EDX). This study demonstrates the feasibility of using fruit wastes for the synthesis of AgNPs.
