AB  - A multiple monolithic fiber solid-phase microextraction (MMF-SPME) utilizing 
      polymeric ionic liquid-based adsorbent was prepared. The adsorbent was obtained 
      by in situ copolymerization of an ionic liquid, 1-trimethyl-(4-vinylbenzyl) 
      aminium chloride and dual cross-linkers (divinylbenzene and 
      ethylenedimethacrylate). The effect of preparation conditions including the 
      content of ionic liquid and porogen in the polymerization mixture on extraction 
      performance was studied in detail. Infrared spectroscopy, elemental analysis, 
      scanning electron microscopy and mercury intrusion porosimetry were used to 
      inspect the physicochemical properties of the new adsorbent. The applicability of 
      the new MMF-SPME was demonstrated by the extraction of trace endocrine disrupting 
      chemicals (EDCs). Results indicated that the prepared MMF-SPME could extract EDCs 
      effectively through multi-interactions such as ion-exchange, pi-pi and hydrophobic 
      interactions. After optimization of extraction parameters, a method of MMF-SPME 
      coupled to high performance liquid chromatography/diode array detection was 
      conducted to detect trace EDCs in complicated samples including environmental 
      water and human urine. The limits of detection (S/N=3) and quantification 
      (S/N=10) for targeted compounds were 0.011-0.065mug/L and 0.036-0.21mug/L, 
      respectively. Satisfactory precision was also achieved by evaluating the 
      repeatability and intermediate precision with relative standard deviations (RSDs) 
      of less than 9% and 10%, respectively. At the same time, the proposed method was 
      successfully applied for the determination of EDCs in water and human urine with 
      spiking recoveries ranged from 70.6% to 119%.
