ABSTRACT Ion- imprinting technology was utilized in the fabrication of copper ion-imprinted sorbent derived from chitosan. Metformin was used to make a complex with the metal (copper ion), then added to the mixture of Chitosan dissolved in 1% (v/v) acetic acid solution, which then form the corresponding polymeric complex. The imprinting was then achieved upon cross-linking and eliminating the incorporated Cu(II) ions to finally have the Cu(II) ion-imprinted sorbent material (Cu(II)-IIP). The material was investigated/ characterized using various techniques such as FTIR, SEM and EDS. Surface Scanning Electron Microscopy (SEM) images of imprinted beads had pore structure, large surface and contact area, making it fit for adsorption. The obtained imprinted beads was examined to evaluate its selective affinity to capture the target Cu(II) ions. The tendency of the developed sorbent toward the targeted Cu(II) ions was compared to the control non-imprinted beads (Cu(II)-NIP). In addition, effects of adsorption pH were studied. Finally, the reusability and selectivity of Cu (II)-IIPs was studied. The formed copper imprinted polymer bead has a removal efficiency of 96.68% for copper ion under selected operational parameters, confirming its suitability for copper ion contaminant in water and wastewater.
