AB  - A rapid and sensitive method for the determination of 171 pesticides in cowpea 
      was developed using multi-walled carbon nanotubes (MWCNTs) as reversed-dispersive 
      solid-phase (r-DSPE) extraction materials. The clean-up performance of MWCNTs was 
      proved to be obviously superior to PSA and GCB. This method was validated on 
      cowpea spiked at 0.01 and 0.1mgkg(-1) with five replicates. The mean recoveries 
      for 169 pesticides ranged from 74% to 129% with relative standard deviations 
      (RSDs) (n=5) lower than 16.4%, except diflufenican and quizalofop-ethyl. Good 
      linearity for all pesticides was obtained with the calibration curve coefficients 
      (R(2)) larger than 0.9970. The limit of detection (LODs) and limit of 
      quantification (LOQs) for the 171 pesticides ranged from 0.001 to 0.003mgkg(-1) 
      and from 0.002 to 0.009mgkg(-1), respectively. The method was demonstrated to be 
      reliable and sensitive for the routine monitoring of the 171 pesticides in cowpea 
      samples.
