Heavy metal ions is a pollutant that is harmful to human health. Its presence in the environment with in trace level concentration. Thats condition make the heavy metal pollutant difficult to analyze. Ion imprinted polymers (IIPs) is a very promising material for application in preconcentration techniques because it potentially has a good selectivity and specificity. The presence of memory effect between metal ions with a specific ligand is the cause of the IIPs has good selectivity. The purpose of this study is to synthesize metal ion imprinted polymer for Cd (II) (Cd-IPs) through the polymerization reaction of salicylic acid and formaldehyde in the presence of metal complexes of Cd (II)-4-(2-pyridylazo) resorcinol. To achieve this objectives, the method will be carried out in 3 steps. They are namely the formation of binary metal complexes with ligands, copolymerization binary complex with <br /> <br /> <br /> salicylic acid and formaldehyde, and characterization of Cd-IPs. Characterization of NIPs, IIPs, and Cd-IPs using FTIR indicates that the polymerization in NIPs and IIPs have been formed as shown by the presence of CH2 bridge vibration wich not found in salicylic acid spectrum as monomer. Shift of vibration band of C=O and N=N on Cd-IPs and IIPs suggests there has been a release of Cd ions by the addition of EDTA. Cd-IPs has a good <br /> <br /> <br /> high selectivity with presence the ion interference such as Pb(II), Cu(II) and Zn(II). Characterization of Cd-IPs retention using the batch method at pH 5 with contact time of 10 minutes shows that the adsorption capacity is 12,38 mg/g Cd-IPs.
