AB  - Polydimethylsiloxane (PDMS)/MIL-100(Fe) coated stir bar was prepared by sol gel 
      technique, and good preparation reproducibility was achieved with relative 
      standard deviations (RSDs) ranging from 2.6% to 7.5% (n=7) and 3.6% to 10.8% 
      (n=7) for bar-to-bar and batch-to-batch, respectively. Compared with commercial 
      PDMS coated stir bar (Gerstel) and PEG coated stir bar (Gerstel), the prepared 
      PDMS/MIL-100(Fe) stir bar showed better extraction efficiency for target 
      triazines compounds. It also exhibited relatively fast extraction/desorption 
      kinetics and long lifespan. Based on it, a method of PDMS/MIL-100(Fe) coated stir 
      bar sorptive extraction (SBSE)-high performance liquid chromatography-ultraviolet 
      detector (HPLC-UV) was developed for the determination of six triazines 
      (simazine, atrazine, prometon, ametryn, prometryne and prebane) in environmental 
      water samples. Several parameters affecting SBSE of six target triazines 
      including extraction time, stirring rate, sample pH, ionic strength, desorption 
      solvent and desorption time were investigated. Under the optimal experimental 
      conditions, the limits of detection (LODs, S/N=3) were found to be in the range 
      of 0.021-0.079mugL(-1). The repeatability RSDs were in the range of 2.3-6.3% (n=7, 
      c=0.5mugL(-1)) and the enrichment factors (EFs) ranged from 51.1 to 102-fold 
      (theoretical EF was 200-fold). The proposed method was applied to the analysis of 
      target triazines in environmental water samples, with recoveries of 98.0-118% and 
      94.0-107% for spiked East Lake water and local pond water samples, respectively.
