Sorption of aqueous Pb2+ ion on synthetic manganese oxides-intercalated with exchangeable cations
E-mail:
This paper describes the preparation, characterization, and application of three different synthetic
manganese oxides (K-MO, H-MO, and Mg-MO). K-MO was synthesized by the reduction of potassium permanganate in an aqueous acidic medium. H-MO was prepared by an ion exchange reaction of K-MO with H+, while Mg-MO was prepared by reaction of H-MO and an aqueous Mg2+ salt solution under reflux. The subsequent solid products were characterized by a chemical composition analysis, XRD, XPS, FT-IR, SEM, and BET measurements. XPS spectra revealed that only tetravalent manganese ions coordinated octahedrally with oxygens. XRD patterns showed that K-MO turned into a layer-structured material while Mg2+ ions were incorporated into the gallery space of the tunnel-structured Mg-MO. Each type ofmanganese oxide was used in a sorption study of aqueous Pb2+ at 25℃ . The sorption of Pb2+ ions by manganese oxide resulted in increases of the concentrations of pre-intercalated ions (potassium ions, protons, or magnesium ions) and Mn2+ ions. In spite of the smaller surface area and pore volume, K-MO showed greater sorption capacity for Pb2+ ions than that of Mg.MO under the present experimental conditions, thus suggesting that ion exchange is the main mechanism for the sorption of Pb2+ ions on manganese oxides. The results are anticipated to be applicable to the removal of heavy metal ions from wastewater and the prevention of migration of ions in landfill leachates.
