Zirconium dioxide polyaniline nanocomposite were prepared through sol-gel method. The chemical structure and morphology of nanocomposite was analyzed through XRD, FTIR and SEM. It was examined how the catalytic activity of synthesized nanoparticles removed Malachite green. For investigation of the removal efficiency of Malachite green by ZrO2 nanocomposite, the concentration of Malachite green, time, amount of adsorbent and pH were measured. The absorption level was evaluated by Langmuir and Freundlich equations.
