Abstract

Na-bentonite(NB)/poly(2-acrylamido-2-methylpropanesulfonicacid)(AMPS) composite were prepared as an adsorbent for the removal of Pb (Ⅱ) from aqueous solutions. Pb (II) adsorption on the composite is a fast process and follows well the pseudo-second-order kinetics. The FTIR spectra indicate NB and poly(AMPS) are simultaneously operating, and chelation should be the dominating adsorption mechanism.
