Synthesis of ZnO Nanoparticles from Goat Slaughter waste for Environmental Protection

Abstract

In this study, a novel technique of utilizing effectively the goat slaughter waste is reported with a conviction that dead animals and their tissue and/or organ wastes too can participate in nanoparticle synthesis. This effort may help in controlling the environmental pollution and subsequently the different diseases. A simple environment friendly protocol, employing the broth of goat slaughter waste (principally intestine) yielded ZnO nanoparticles. X-ray and transmission electron microscopy analyses are performed to ascertain the formation of ZnO nanoparticles. Individual nanoparticles as well as a few aggregates having the size of 3-11 nm are found. Also, the reaction protocol was monitored using UV-visible spectroscopy. Accordingly, the entire span of experimentation (absorbance–time data) has been proposed in the form of a mathematical model. The surface plasmon resonance was observed at 359 nm. A possible involved mechanism for the biosynthesis of ZnO nanoparticles has also been proposed.
