摘要：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. 7H 2 O. 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.
