| Abstract: | Graft copolymerization of acrylic acid on carboxymethylcellulose, using potassium persulfate as the intiator and N,N'-methylenebisacrylamide as the cross-linking agent, was prepared from carboxymethylcellulose and acrylic acid by the method of copolymerization and cross-linking, and applied to Cr(VI) absorbefacient. The results showed that the adsorption rate was more than 95%, when PH=4.5, adsorbent period was 2 hours and concentration of Cr(VI) was 100mg/L. |
