520 _aThe aim of this thesis is to verify the applicability of manufactured oxides (titanium dioxide, aluminum oxide, and zinc oxide) for removing lead salts from aqueous solutions by conducting a number of batch experiments on the effect of pH, dose, contact time, initial concentration, and temperature. As well as the analyses of adsorption kinetics, adsorption mechanisms, and adsorption thermodynamics are studied.The adsorption efficiencies were found to be dependent on the parameters which were investigated through the experiments.The adsorption kinetics of Pb(II) were studied by common models, the experiments were found that lead uptake using all adsorbents can be fitted by PSO model. The adsorption isotherms of Pb (II) were studied by common models.The experiments were found that lead uptake using all adsorbents can be well fitted by Langmuir model in the case of titanium dioxide and zinc oxide. But in the case of aluminum oxide, D-R was well fitted. Also the heat of adsorption of Pb (II) for all adsorbents implied that the adsorption was endothermic in nature due to the positive values of enthalpy (xH{u00B0}). The absorbents were characterized using (SEM) and (EDX) in order to conduct investigation on adsorbents with results ensuring adsorption occurrence. Therefore, based on practical experiences, it was found that the best adsorbent to uptake lead from synthetic waste water is zinc oxide followed by titanium dioxide and aluminum oxide
