Auto-combustion synthesis and characterization of zirconium oxide nanoparticles for removal of crystal violet dye from aqueous solution

Abstract

In the present work, zirconium oxide nanoparticles were synthesized via auto-combustion method using urea. Fourier transform infrared spectroscopy (FTIR), X-Ray diffractometry (XRD), High resolution transmission electron microscopy (HR-TEM) as well as Field emission scanning electron microscopy (FE-SEM) were used to elucidate the structure and morphology of the synthesized zirconium oxide nanoparticles. The synthesized ZrO 2 nanoadsorbents were used for crystal violet removal from aqueous solution. Various parameters were checked in a batch method for the adsorption process of crystal violet dye on zirconium oxide adsorbents such as pH solution, duration time, ZrO 2 dose (adsorbents), initial dye concentration as well as temperature. The adsorption kinetics, isotherm models and thermodynamic parameters were discussed.
