The adsorption of Cd (II), Ni (II) and Cu (II) ions on nanoϒ-Al2O3 isotherms study indicate that (Langmuir, Freundlich and  Elovich) be the most excellent model described removal of Cu (II) ion. Jovanovic and Harkins-Jura were found to be the most excellent one described removal of Ni (II) ions and the all models are less suitable for Cd (II) ions. All these were noted from the correlation coefficients values. The highest removal percentages obtained for ions were 92.045 % of Cd (II), 93.175 % of Ni (II) and 93.685% of Cu (II). FESEM was measured to find out the average particle size of nanoparticles and EDXA was used for measuring purity.

Keywords: Langmuir, Freundlich, Elovich, Jovanovic, removal, ternary, Cd (II), Ni (II), Cu (II) ions.
