Abstract: A Cd2+ Ion Imprinted Polymer (Cd-IIP) has been synthesized by copolymerizaton of cadmium ion, quinaldic acid (complexing agent), 4-vinyl pyridine (monomer), dimethyl sulfoxide (solvent), ethyleneglycoldimethacrylate, EGDMA (cross-linker) and 2,2-azobis-isobutyronitrile, AIBN (initiator). Polymerization was conducted using a microwave at a temperature of 70 °C with heating times of 45 minutes. The template (Cd2+) was removed by leaching the template with ethanol and 4 M HCl, washed by aquabidest and dried in an oven at the temperature of 60 °C. The polymer particles (imprinted and nonimprinted) were characterized using fourir transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS). The result showed that using heating time 45 minutes at temperature 70 °C, the particle morphology is viewed like as the large homogeneous. So, the imprinted polymer had bands at 3483 cm-1 ,1726 cm-1, and 1155 cm-1 indicating the presence of OH, C=O and C-O, respectively.
