AB  - An organic-inorganic hybrid monolithic column doped with gold nanorods (AuNRs) 
      was prepared and evaluated for solid phase extraction (SPE) of polycyclic 
      aromatic hydrocarbons (PAHs). Excellent dispersibility of AuNRs in binary green 
      porogen system consisting of 1-hexyl-3-methylimidazolium tetrafluoroborate and 
      deep eutectic solvents (DESs) was confirmed by energy dispersive spectrometry 
      (EDS). The particle size of the resulting AuNRs (70-90 nm) was thoroughly 
      examined by a transmission electron microscopy (TEM). The redox system including 
      ammonium persulfate (APS) and tetramethylethylenediamine (TEMED) was used to 
      initiate in situ polymerization at 4  degrees C to prepare the hybrid monolith. The 
      mesoporous structure of the AuNR hybrid monoliths was confirmed by scanning 
      electron microscopy (SEM) and nitrogen adsorption. With enrichment factors (EFs) 
      of 150- to 292-fold, the developed method was successfully applied to the 
      determination of 10 PAHs in wastewater samples. The recoveries at a spiked level 
      were in the range 84.9 to 99.5% with limit of detections (LODs) and relative 
      standard deviations (RSDs) ranging from 0.02 to 0.10 mug L(-1) and 1.5 to 4.2%, 
      respectively. The correlation coefficients (R(2)) for the calibration 
      function obtained were better 0.9991 for the target compounds. Compared to the 
      AuNR-free monolith, the extraction efficiency of the AuNR-incorporated monolith 
      is more than two times higher. The results indicated that the doping of AuNRs is 
      an effective approach to obtain the hybrid monolithic column with good separation 
      ability for PAHs. Graphical abstract.
