Performance of magnesium oxide-coated bentonite in removal process of copper ions from aqueous solution
چکیده انگلیسی

This paper presents the adsorption of Cu(II) ions from aqueous solution on modified Unye bentonite. Adsorption of Cu(II) ions by magnesium oxide-coated bentonite (MCB) sample was investigated as a function of the initial Cu(II) concentration, solution pH, ionic strength, temperature and inorganic ligands (Cl−, SO42−, and HPO42−). Changes in the surfaces and structure were characterized by means of XRD and N2 gas adsorption data. The Langmuir monolayer adsorption capacity of MCB in 0.1 M KNO3 solution was estimated as 58.44 mg/g. ΔG, ΔH and ΔS values were evaluated for MCB to be −9.50 kJ/mol (at 303 K), 43.81 kJ/mol and 175.85 J/mol K.
