AB  - In this study, a novel ionic liquid-type surfactant modified attapulgite named as 
      1-dodecyl-3-methylimidazolium bromide-attapulgite (C(12)MIM-ATP) is successfully 
      prepared and applied in dispersive solid phase extraction (dSPE) for the fast 
      determination of pyrethroid residues in tea drinks. The primary factors that 
      influenced the extraction efficiency, including sorbent type, amount of sorbent, 
      extraction time, desorption conditions, pH and ionic strength, are investigated. 
      The optimized results reveal that the extraction and desorption equilibria are 
      rapidly obtained within 1 min. Under the optimized conditions, good linearity 
      (2-500 mug/L) is observed for four pyrethroids in tea drinks with determination 
      coefficients (r(2)) ranged from 0.9992 to 1.0000. The limits of detection (LODs) 
      are 0.6 mug/L for all pesticides. Acceptable extraction recoveries of target 
      analytes are found from 90.28 to 107.56% with relative standard deviations (RSDs) 
      less than 8.30% in real tea drink samples. The batch-to-bath repeatability is 
      evaluated by recovery test on five independent synthesized C(12)MIM-ATP sorbents. 
      Satisfactory batch-to-batch repeatability is obtained with the recovery factors 
      varied in 15%. A small matrix effect is observed using C(12)MIM-ATP as the 
      sorbent for detection pyrethroids in tea drinks.
