| 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 ZrO2 nano-adsorbents 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, ZrO2 dose (adsorbents), initial dye concentration as well as temperature. The adsorption kinetics, isotherm models and thermodynamic parameters were discussed. | ||||
