AB  - A new method for the analysis of estrogens including estrone (E1), 17b- estradiol 
      (E2) and diethylstilbestrol (DES) in aqueous samples was performed using 
      dispersive liquid liquid microextraction (DLLME) and high- performance liquid 
      chromatography (HPLC). In order to optimize DLLME some important parameters such 
      as type and volume of extraction and disperser solvent, extraction time, ionic 
      strength and pH of sample were studied and optimum condition was obtained. Under 
      optimum condition (extraction solvent: 80 microL CCl4; dispersive solvent: 1.25 mL 
      acetone; NaCl: 12% (w/w) and pH of sample = 10.0), the enrichment factors and 
      extraction recoveries were 71.0-78.5 and 85.2-94.2 respectively. Linearity was 
      observed in the range of 0.02-500.0 microg L-1 for DES and 0.03-500.0 microg L-1 for E1 
      and E2. Limits of detection were 0.008 microg L-1 for DES and 0.010 microg L-1 for E1 and 
      E2. The relative standard deviations (RSDs) for determination of estrogens in 
      water were in the range of 2.4-3.2% (n = 5).
