AB  - In this work, a novel type of polymeric ionic liquid (PIL)-based magnetic 
      adsorbent was successfully synthesized and applied for the extraction and 
      determination of seven inorganic anions in water samples by coupling with ion 
      chromatography. The new adsorbent was synthesized by simple free radical 
      copolymerization of 1-ally-3-vinylimidazolium chloride, ethylene glycol 
      dimethacrylate and silica-coated magnetite. The adsorbent exhibited well-defined 
      core-shell structure and good magnetic response ability. Furthermore, due to the 
      presence of abundant anion-exchange groups in the PIL, the adsorbent displayed 
      expected extraction performance for anions including F(-), Cl(-), Br(-), NO2(-), 
      NO3(-), PO4(3-) and SO4(2-). Various experimental parameters that could affect 
      the extraction performance, such as the amount of adsorbent, desorption solvent, 
      extraction and desorption time, the pH value of sample solution were investigated 
      in detail. Under the optimized conditions, low limits of detection (S/N=3) and 
      quantification limits (S/N=10) of the proposed method for the target anions were 
      achieved within the range of 0.061-0.73mug/L and 0.19-2.41mug/L, respectively. The 
      repeatability was investigated by evaluating the intra-day, inter-day precisions 
      and batch-to-batch reproducibility with relative standard deviations (RSDs) lower 
      than 11%. At the same time, the method also showed high extraction speed, 
      simplicity, practicality and low cost for the extraction inorganic anions. 
      Finally, the proposed method was used to detect anions in different water samples 
      successfully. The recoveries were in the range of 71.0-111%, and the RSDs were 
      below 12% in the all cases.
