A series of gel resins were prepared by polymerizing glycidyl methacrylate (GMA) and 2‐acrylamido‐2‐methylpropane sulfonic acid (AMPS) and functionalizing with ammonia (NH 3 ) and tetraethylenepentamine (TEPA). The aminated gel resins were then used as an adsorbent for the removal of heavy metal ions (Cu 2+ and Pb 2+ ). These gel resins containing amino groups and chelating amino groups had excellent adsorptive properties for Cu 2+ and Pb 2+ . The adsorption process reached equilibrium in 40 min, and the adsorption capacities of Cu 2+ and Pb 2+ were 75.0 mg g −1 and 266.6 mg g −1 for the NH 3 ‐aminated gel resins and 57.5 mg g −1 and 330.6 mg g −1 for the TEPA‐aminated gel resins, respectively. After five adsorption–desorption processes, the adsorption capacities only decreased slightly. Thus, these aminated gel resins can be used as effective adsorbents for aqueous heavy metal ions (Cu 2+ and Pb 2+ ). © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017 , 134 , 44466.
