摘要

Na-bentonite/poly AMPS composite were prepared as an adsorbent for the removal of Pb (Ⅱ) from aqueous solutions.Pb (Ⅱ) adsorption experiments show the optimum pH and the bentonite content are pH 4.0 and 5g Na-bentonite/10g AMPS,respectively.Experimental data were described by Langrnuir and Freundlih isotherms,and the correlation coefficient (R2) shows that the adsorption follows the Freundlich adsorption model.
