Synthesis And Characterization Of An Ion Imprinted Polymer For Cadmium Using Quinaldic Acid As Complexing Agent And Applying By Microwave

Abstract A Cd2 Ion Imprinted Polymer Cd-IIP has been synthesized by copolymerizaton of cadmium ion quinaldic acid complexing agent 4-vynil pyridine monomer dimethyl sulfoxide solvent ethyleneglycoldimethacrylate EGDMA cross-linker and 22-azobis-isobutyronitrile AIBN initiator. Polymerization was conducted using a microwave at a temperature of 70 oC 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 60oC. 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 oC 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 CO and C-O respectively.
