SYNTHESIS, STUDY STRUCTURAL CHARACTERISTICS AND ADSORPTION OF ION MN2+ ON NANOPARTICLES Fe3+ DOPED ZnO

Abstract

    Iron-doped ZnO (IDZ) nanopowders have been synthesized by the low-temperaturecombustion method using poly (vinyl alcohol) (PVA). The synthesized powder wascharacterized by X-ray diffraction (XRD), transmission electron microscopy through(TEM), high energy scattering (EDX). The XRD spectra show that all the samples arehecxagonal wurtzit structures. Iron doped ZnO powders with crystallite size of 30 nmhave been prepared.Influences of contact time, initial concentration of the adsorbate, volume of materialand the percentage of iron-doped were experimentally. The nanosized Fe3+ dopedZnO material yielded maximum sorption capacity 153,85 mg/g for ion Mn2+according to the Langmuir isotherm.
