Abstract: Magnetic ion imprinted materials (Fe3O4@SiO2@IIM) were synthesized by emulsion polymerization along with magnetic non-ion imprinted materials (Fe3O4@SiO2@NIIM), followed by characterization via various analytical techniques. The prepared Fe3O4@SiO2@IIM are well uniform and monodispersed, with the particle size of about 20 nm, featuring with super-paramagnetism. Based on the as-prepared Fe3O4@SiO2@IIM, a novel method of ion imprinted magnetic solid phase extraction (IIMSPE) combined with graphite furnace atomic absorption spectrometry (GFAAS) detection was developed for the determination of trace Ni(II) in environmental water samples. The factors affecting the extraction, such as pH of sample solution, concentration of elution, elution volume, elution time, sample volume, extraction time were investigated in detail. Under the optimized conditions, the limit of detection was 0.015ngˇmL-1, with relative standard deviation of 7.3% (c=0.1, ngˇmL-1) and enrichment factor of 24.8. The prepared Fe3O4@SiO2@IIM could be used more than 5times. For the validation of the proposed method, certified reference material GSBZ50009-88 (environmental water) was analyzed and the determined value was in good agreement with the certified value. The developed method was applied to the analysis of Ni(II) in Yangtze River water and East Lake water, and the recoveries for the spiked samples were in the range of 90.6%-107.2%, indicating a good application potential of the proposed method for the quantification of trace Ni(II) in environmental water samples.
