Abstract

The surface characterization of nickel oxide was performed using various physicochemical methods. Batch adsorption technique was used to measure the adsorption of calcium onto NiO. The adsorption experiments of Ca by NiO were conducted at different temperatures and concentrations of the metal ion. The effect of pH on Ca removal from aqueous solution was also studied to observe the sorption behavior of NiO at different pH values. Langmuir model was used to interpret the cation exchange sorption of Ca onto NiO. The proton stoichiometry wits derived from Kurbaatov-type plot. The isosteric heat of adsorption (?H) revealed that adsorption process was endothermic.
