      polycyclic aromatic hydrocarbons].
PG  - 455-60
AB  - A C6-silica hybrid monolithic column was prepared by click reaction with 
      capillary silica monolith. Firstly, an azide-functionalized silica monolithic 
      column was synthesized via sol-gel reaction with tetramethoxysilane (TMOS) and 
      3-azidopropyltrimethoxysilane (N3PTMS). Then 1-hexyne was covalently immobilized 
      on the capillary monolith by the "azide-alkyne" click reaction to form C6-silica 
      hybrid monolithic column. As an extraction media of polycyclic aromatic 
      hydrocarbons (PAHs), the conditions for the preparation and modification of the 
      monolith were carefully investigated according to the extraction efficiency. The 
      enrichment factors for typical PAHs: naphthalene, phenanthrene, pyrene and benzo 
      a pyrene finally reached 95.9, 14.2, 103.2 and 57.8, respectively. The relative 
      standard deviations (RSDs) for the extraction were lower than 5.5% (intra-day, t 
      = 8) and 7.3% (inter-day, n = 10). Based on the in-tube solid phase 
      microextraction (in-tube SPME), a new determination method for 16 PAHs was 
      developed with high performance liquid chromatography (HPLC). The limits of 
      detection (LODs, SN = 3) were 0.08-3.72 microg/L and the limits of quantification 
      (LOQs, S/N = 10) were 0.26-12.40 microg/L for the PAHs. The spiked recoveries for the 
      PAHs in soil samples were between 82.4% and 110.6% with the RSDs (n = 3) of 
      2.6%-7.9%. Comparison with the method of United States Environmental Protection 
      Agency (U. S. EPA) for the PAIs determination in soil samples, the results showed 
      good accuracy and high consistency. And the high extraction efficiency with high 
      sensitivity and convenience was also demonstrated in the applications of the new 
      approach.
