The parameters affecting preconcentration like pH, adsorption time, amount of sorbent, elution solvent, eluent volume and concentration and desorption time were optimized. Following the sorption and elution steps, Cd(II) ion was quantified by flame atomic absorption spectrometry. The limit of detection (LOD) and the relative standard deviations (RSDs) were 0.3 μg L-1 and 3.45% -5.63% (inter-day and intra-day), respectively. The sorption capacity of ion imprinted polymer was 66.35 mg g-1 for Cd(II) ion. Finally, the proposed method was applied for determination of Cd(II) ion in water, soil and food samples.
