Samples characterized using Fourier transform infrared spectrophotometry (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectrometer (EDX). By Fourier transform infrared FT-IR has proven bond forming of NiO in nickel oxide. X-ray diffraction pattern (XRD) show that nanoparticles have single phase in cubic crystalline network. The size of the nanoparticles is about 57 nm. UV-VIS show that the compound can be used as an efficient Adsorbent for the removal of Aluminon in Aqueous solution. The highest efficiency accrued in 5 ppm solution and pH=3. The Obtained empirical data in optimum condition was used to model the behavior of absorption in five isotherm equations such as: Langmuir, Freundlic –Langmuir, Toth and Khan. The adsorption data were fitted well to the Langmuier isotherm. The kinetics of adsorption interactions were examined with two adsorption mechanisms, pseudo-first-order, pseudo second-order. Result show that the adsorption data has the most conformity with, pseudo-second-order model.
