AB  - A green, simple and sensitive hydrophobic DES-based dispersive liquid-liquid 
      microextraction coupled with high-performance liquid chromatography (HPLC) was 
      developed for the analysis of neonicotinoid insecticide residues in various 
      samples. A hydrophobic deep eutectic solvent (DES) was synthesized using decanoic 
      acid as a hydrogen bond donor and tetrabutylammonium bromide (TBABr) as a 
      hydrogen bond-acceptor. DESs were synthesized and characterized by Fourier 
      transform-infrared (FTIR) spectroscopy. Two disperser solvents were substituted 
      with surfactants and acetonitrile, which could afford more effective 
      emulsification and make the extraction relatively greener. The hydrophobic DES 
      extraction phase occurred 10 min after centrifugation, being easy to be collected 
      for analysis. Several parameters were investigated and optimized. Under the 
      optimum condition, the calibration curve of this method was linear in the range 
      of 0.003-1.0-microg.mL(-1), with a correlation coefficient (R(2)) higher than 0.99 
      and a good repeatability, with the relative standard deviations (RSDs) were less 
      than 5.00%. The limits of detection were in the range of 0.001-0.003 microg.mL(-1); 
      the limits of quantitation were in the range of 0.003-0.009 microg.mL.mL(-1). 
      Finally, the presented method was implemented to determine the neonicotinoid 
      insecticide residues in water, soil, egg yolk samples and acceptable recoveries 
      were obtained.
