AB  - In this work, a novel type of magnetic polymer particle, magnetic poly(diethyl 
      vinylphosphonate-co-ethylene glycol dimethacrylate) [Fe(3)O(4)@p(DEVP-co-EDMA)], 
      was successfully synthesized and applied for the extraction and determination of 
      chlorophenols in water samples by coupling with high-performance liquid 
      chromatography (HPLC). Fe(3)O(4)@p(DEVP-co-EDMA) was synthesized by a simple 
      seeded radical polymerization method and exhibited well-defined core-shell 
      structure and good magnetic response ability. In addition, the magnetic polymer 
      had the advantages of abundant adsorption sites and high enrichment efficiency. 
      Due to the presence of PO group in the skeleton of polymer, the magnetic polymer 
      material displayed excellent extraction performance for chlorophenols, such as 
      2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP) and 2,4,6-trichlorophenol 
      (2,4,6-TCP). Hydrophobic skeleton of the magnetic polymer also provided strong 
      interaction with the target analytes, especially pentachlorophenol (PCP) which is 
      a kind of non-polar chlorophenol. Desorption solution, pH of water sample, 
      extraction time and desorption time, the amount of adsorbent, and the volume of 
      desorption solution were optimized. Under the optimized conditions, the linear 
      ranges of four chlorophenols were 2-500 ng/mL with the limits of detection 
      (S/N=3) ranging from 0.20 to 0.34 ng/mL. The repeatability was investigated by 
      evaluating the intra- and inter-day precisions with relative standard deviations 
      (RSDs) lower than 15.0%. The recoveries for real water samples were in the range 
      of 92.7-108.0%. Collectively, the results indicated that the novel 
      Fe(3)O(4)@p(DEVP-co-EDMA) was successfully applied in the extraction and 
      detection of chlorophenols from water samples, and the magnetic polymer particle 
      showed potential applications in the analysis of polar compounds.
