Adsorption Kinetics of Pb (Ⅱ) onto Na-Bentonite/poly AMPS composite

摘要：

　　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.
