摘要：

The equilibrium isotherms of zinc adsorption onto natural bentonite show that the data correlate well with Freundlich and Langmuir models and that the adsorption is physical in nature. The operating parameters (agitation-speed, solid-liquid ratio, temperature, particle size and initial zinc concentration) influenced the rate of adsorption. The maximum monomolecular capacity eo according to the Langmuir model is 52.91 mg g(-1) for an initial zinc concentration of 300 mg L(-1) at 20 degrees C. (C) 1997 Published by Elsevier Science Ltd.
