| Abstract: | The Poly(2-acrylamide-2-methylpropanesulfonic acid-co-acrylic acid) superporous hydrogels were synthesized by using 2-acrylamide-2-methylpropanesulfonic acid(AMPS) and acrylic acid(AA) as monomers.The structure of material were analyzed by FTIR and SEM.The properties of absorbing several heavy metal ions were discussed,including Fe3+,Pb2+and Cu2+.The result showed that the adsorption capacity and removal rate of Fe2+ could reach 4.2 mmol/L and 90.5%,and of Pb2+ reach 2.5 mmol/L and 81.2%,and of Cu2+ just reach 2.1 mmol/L and 69.3% respectively. |
