Synthesis, characterization and application of zinc oxide nanoparticles (n-ZnO)

Abstract

In present study, zinc oxide (n-ZnO) nanoparticles were synthesized by simple solution based approaches. Synthesized n-ZnO particles were characterized by XRD, TEM, SEM and FTIR. XRD and TEM confirmed the formation of nanosized zinc oxide particles in the size range of 18-31 nm. n-ZnO nanoparticles were used for the removal of Cd(II) from aqueous solutions. A high (92%) removal Cd(II) from its aqueous solutions with initial concentration of 200 mg/L by n-ZnO particles was achieved. Further, the nanoparticles were efficient at other concentrations also. © 2013 Elsevier Ltd and Techna Group S.r.l.
