AB  - Dispersive liquid-liquid microextraction and gas chromatography-flame photometric 
      detection (DLLME-GC-FPD) were performed for the speciation of butyl and phenyltin 
      compounds in water samples after derivatization with sodium tetraethylborate 
      (NaBEt4). Some important parameters, such as pH, amount of NaBEt4, derivatization 
      time, kind and volume of extraction and disperser solvents, extraction time and 
      salt effect were investigated and optimized. High enrichment factors (825-1036) 
      and low detection limits (0.2-1 ng L(-1)) were obtained under the optimum 
      conditions. The calibration graphs were linear in the range of 0.5-1000 ng L(-1) 
      (as Sn) for the target analytes. The relative standard deviations (RSDs) for the 
      extraction of 20 ng L(-1) (as Sn) of butyl and phenyltin compounds varied from 
      2.3 to 5.9% (n=7) and from 4.1 to 8.8% (n=7) with and without using internal 
      standard, respectively. Seawater and river water samples were successfully 
      analyzed using the proposed method and the relative recoveries of the studied 
      compounds in the water samples, at spiking levels of 10.0 and 100 ng L(-1) (as 
      Sn) were obtained to be 82.5-104.7%.
