      determination of chlorophenols in environmental water samples by liquid 
      chromatography.

AB  - Magnetic microsphere confined ionic liquid was synthesized by covalently bonding 
      N-methylimidazolium on magnetic microspheres. The functionalized magnetic 
      microspheres were characterized by Fourier transform infrared (FT-IR) 
      spectrometry, thermogravimetric analysis (TGA) and scanning electron microscopy 
      (SEM). The prepared material was used for the preconcentration of three 
      chlorophenols (CPs) in water combined with high-performance liquid chromatography 
      (HPLC). Several conditions that probably affected the extraction efficiency such 
      as standing time, eluent and its volume, sample pH and volume, were optimized. 
      Under the optimal conditions, good recoveries (70.3-88.8%) were achieved with 
      satisfactory relative standard deviations (RSDs) of less than 6.0%. The limits of 
      detection for the three CPs were 0.20-0.35 mug L(-1). The results indicated that 
      the ionic liquid-functionalized magnetic microspheres show significant promise 
      for the analysis of CPs in environmental samples.
