| 中文摘要 | To clarify the effect and mechanism of pillared montmorillonite on Cd(2+) adsorption in aqueous solution, carbon modified alumina-pillared montmorillonite has been prepared by incorporating hydroxyl-aluminum cations into the lamellar spaces of montmorillonite via ion-exchanging together with polyvinyl alcohol (PVA), followed by calcining in N(2) atmosphere. The pillared montmorillonites were characterized by XRD, FT-IR, TG-DTA and sorption isotherms. Uptake of Cd(2+) from aqueous solution was analyzed by means of atomic absorption spectroscopy. The experimental results indicated that the pillared montmorillonites show better properties on both Cd(2+) adsorption and desorption than the unpillared, which made them the promising recycling Cd(2+) adsorbents. Moreover, adjusting the pH value of the solution could control the adsorbed amount of Cd(2+). The adsorption process fitted the second-order kinetics well, and the two isotherm equations due to Freundlich and Langmuir showed good fits with the experimental data. (C) 2008 Elsevier B.V.
