| 英文摘要 | The optimal preparation conditions for Al-13-Pillared acid-activated Na+-montmorillonite (Al-13-PAAMt) were (1) an acid-activated Na+-montmorillonite (Na+-Mt) solution of pH 3.0, (2) a OH-/Al3+ molar ratio of 2.4 and (3) Al3+/Na+-Mt ratio of 1.0 mmol g(-1). The effects of OH-/Al3+ and Al3+/Na+-Mt ratios on the adsorption of Cd2+ onto Al-13-PAAMt were studied. A comparison of the adsorption of Cd2+ onto Al-13-PAAMt, Al-13-pillared Na+-montmorillonite (Al-13-PMt) and Na+-Mt suggested that Al-13-PAAMt had higher adsorption affinity for Cd2+ than the other two adsorbents. A pseudo-second-order model described the adsorption kinetics well. Cadmium adsorption followed the Langmuir two-site equation, while desorption was hysteretic. (C) 2007 Elsevier B.V.
