摘要：A series of gel resins were prepared by polymerizing glycidyl methacrylate (GMA) and 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and functionalizing with ammonia (NH3) and tetraethylenepentamine (TEPA). The aminated gel resins were then used as an adsorbent for the removal of heavy metal ions (Cu2+ and Pb2+). These gel resins containing amino groups and chelating amino groups had excellent adsorptive properties for Cu2+ and Pb2+. The adsorption process reached equilibrium in 40min, and the adsorption capacities of Cu2+ and Pb2+ were 75.0mg g(-1) and 266.6mg g(-1) for the NH3-aminated gel resins and 57.5mg g(-1) and 330.6mg 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 (Cu2+ and Pb2+). (c) 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44466.
