A novel hydrogel was successfully synthesized through doping 4A molecular sieve (4A-MS) into poly (acrylic acid-co-acrylamide) and used for the removal of Cu2+, Ni2+, Cd2+and Pb2+in the solution. The composite hydrogel all exhibited high sorption capacity (SC) and high elution percentage (EP) for the four above heavy metal ions. Simultaneously, the water uptake (WU) of the hydrogel was dramatically decreased and the mechanical strength of the absorbent hydrogel was improved with increasing 4A-MS content.
