AB  - In the present study, porous monolith-based magnetism-reinforced in-tube solid 
      phase microextraction (MB-MR/IT-SPME) was first introduced to concentrate 
      sulfonylurea herbicides (SUHs). To realize the effective capture of SUHs, a 
      monolithic capillary microextraction column (MCMC) based on poly 
      (vinylimidazole-co-ethylene dimethacrylate) polymer doped with Fe(3)O(4) magnetic 
      nanoparticles was in-situ synthesized in the first step. After that, the MCMC was 
      twined with a magnetic coil which was employed to carry out variable magnetic 
      field during adsorption and desorption procedure. Various important parameters 
      that affecting the extraction performance were inspected in detailed. Results 
      well indicated that exertion of magnetic field in the whole extraction procedure 
      was in favor of the capture and release of the studied SUHs, with the extraction 
      efficiencies increased from 36.8-58.1% to 82.6-94.5%. At the same time, the 
      proposed MB-MR/IT-SPME was online combined to HPLC with diode array detection 
      (HPLC/DAD) to quantify trace levels of SUHs in water and soil samples. The limits 
      of detection (S/N = 3) for water and soil samples were in the ranges of 
      0.030-0.15 mug/L and 0.30-1.5 mug/kg, respectively. The relative standard 
      deviations (RSDs) for intra- and inter-day variability were both less than 10%. 
      Finally, the introduced approach was successfully applied to monitor the low 
      contents of studied SUHs in environmental water and soil samples. Satisfying 
      fortified recovery and precision were achieved.
