AB  - Sensitive, accurate, and simultaneous determination of nitrobenzene compounds 
      (NBs) in environmental water samples is of great significance due to their high 
      risk to human health. In this work, a new triazine-based hyper-crosslinked 
      polymer named CC-Py was constructed via the Friedel-Crafts reaction between 
      cyanuric chloride (CC), pyridine (Py) and 1,2-dichloroethane. Due to its 
      excellent stability, high surface area and hydrophilic-lipophilic (amphiphilic) 
      structure, the CC-Py exhibited a high affinity toward the NBs (nitrobenzene, 
      2-nitrotoluene, 2,6-dimethylnitrobenzene, 3-nitrotoluene, 4-nitrotoluene, 
      3-nitrochlorobenzene, 4-nitrochlorobenzene, 2-nitrochlorobenzene, 
      2,4-dimethylnitrobenzene, 3-nitrobromobenzene, 4-nitrobromobenzene and 
      4-nitroiodobenzene). Then, a CC-Py based solid-phase microextraction coupled with 
      gas chromatography-flame ionization detection was developed to detect the twelve 
      NBs in real water samples. The results showed that the method had low limits of 
      detection (0.20-0.50 mug L(-1)), good reproducibility (relative standard 
      deviations (RSDs) < 8.6%) and high enrichment factors (967-1590). The recoveries 
      for the NBs in six different types of water samples were between 90% and 111% 
      with the RSDs less than 7.5%. This work provides a facile and sensitive method 
      for the determination of trace level of NBs in real water samples.
