In this research, the Cu(II) doped ZnO/ZnAl2O4 was prepared. The sample was characterized using X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM) equipped with Energy dispersive X-ray spectroscopy (EDX) and Inductivity coupled plasma atomic emission spectroscopy (ICP-AES). Efficiency of the sample as an adsorbent for anionic and cationic dyes removal such as Methyl orange, Congo red, Methylene blue and dyes mixture of Methylene blue and Methyl orange in aqueous solution was investigated. Furthermore, efficiency of this sample with undoped sample was compared. Pseudo- first order and pseudo- second order kinetic models were examined. The results showed that the Cu(II) doped ZnO/ZnAl2O4 sample is a promising candidate for removal of Methyl orange anionic dye from wastewater.
