Grafted copolymerization of acrylic acid on carboxymethylcellulose intermingled with Polyanilineaniline, using ammonium peroxydisulfate as the intiator and N,N'-methylenebisacrylamide as the cross-linking agent, was prepared from carboxymethylcellulose, acrylic acid and aniline by the method of copolymerization and cross-linking, and applied to Pb(II) absorbefacient. The results showed that the adsorption rate was more than 97%, when PH=6, adsorbent period was 45 minutes and concentration of Pb(II) was 100mg/L.
