Green Synthesis and Characterization of nano Zero Valent Iron Using Banana Peel Extract

Abstract

Banana (Musa paradisiaca var. sapientum (L) Kunt.) peels were discarded as inevitable wastes in compsumtion which wasted our resources and no have environment added value. In this paper, we report a novel use of the water peel extract of Banana to produce nano Zero Valent Iron by reduction of FeSO_4.7H₂O. The phytochemicals present in the peel extract served as effective reducing and capping agent. The nZVI were characterized by UV-Visible spectroscopy, Fourier Transform Infra Red (FTIR), Scanning Electron Microscopy (SEM) and X-Ray Energy Dispersive Spectrofotometer (EDS) methods. In the UV–Vis spectrum, the absorption spectra of colloidal nZVI showed a surface plasmon resonance (SPR) peak at a wavelength of 215 nm. Fourier transform infra-red spectroscopy measurements showed the nZVI having a coating of phenolic compounds indicating a possible role of biomolecules responsible for capping and efficient stabilization of the the green synthesized zero-valent iron nanoparticles. SEM and EDS methods confirmed the successful synthesis of the spherical nZVI with diameters of 10–70 nm.
