AB  - A novel method was developed for the determination of captan, folpet, and 
      captafol in apples by dispersive liquid-liquid microextraction (DLLME) coupled 
      with gas chromatography-electron capture detection (GC-ECD). Some experimental 
      parameters that influence the extraction efficiency, such as the type and volume 
      of the disperser solvents and extraction solvents, extraction time, and addition 
      of salt, were studied and optimized to obtain the best extraction results. Under 
      the optimum conditions, high enrichment factors for the compounds were achieved 
      ranging from 824 to 912. The recoveries of fungicides in apples at spiking levels 
      of 20.0 microg kg(-1) and 70.0 microg kg(-1) were 93.0-109.5% and 95.4-107.7%, 
      respectively. The relative standard deviations (RSDs) for the apple samples at 
      30.0 microg kg(-1) of each fungicide were in the range from 3.8 to 4.9%. The 
      limits of detection were between 3.0 and 8.0 microg kg(-1). The linearity of the 
      method ranged from 10 to 100 microg kg(-1) for the three fungicides, with 
      correlation coefficients (r (2)) varying from 0.9982 to 0.9997. The obtained 
      results show that the DLLME combined with GC-ECD can satisfy the requirements for 
      the determination of fungicides in apple samples.
