Abstract: In this work a novel ion imprinted polymer (IIP) based on 4-(vinylamino)pyridine-2,6-dicarboxylicacid (VPyDC), was coated on Fe3O4 nano-particles. The application of this magnetic sorbent was investigated for preconcentration and determination of trace Pb(II) ions by flame atomic absorption spectrometry. Effects of various parameters such as sample pH, adsorption/desorption time and eluent were investigated during this study. The relative standard deviation and limit of detection of the method were found to be 1.8% and 0.9 ng mL-1, respectively. The accuracy of this method was confirmed using various standard reference materials, then it was used for Pb(II) determination in environmental samples
