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.
