Abstract: Amine-functionalized polymeric adsorbents have shown prospect over many other adsorbents and received increasing attention in recent years for the removal of heavy metal ions. In this study, a focus has been placed on poly(glycidyl methacrylate) (PGMA) beads functionalized with various polyamines as the adsorbent. The purpose of the study is to investigate the behaviors and mechanisms of the adsorbent in heavy metal ion adsorption and their relationship with the immobilized different polyamines. The work included the preparation of PGMA beads and their functionalization with a series of aliphatic polyamines with increased numbers of amine groups and molecular chain lengths. Then, adsorption experiments were conducted with the prepared adsorbent for a number of heavy metal ion species. Various advanced analytical technologies were used to characterize the materials and elucidate the reactions or interactions and mechanisms involved in the various processes.
