AB  - This paper describes a new analytical system, based on the combination of 
      continuous flow liquid membrane extraction (CFLME) enrichment and capillary 
      electrophoresis (CE) separation, for analysis of chlorinated phenols in water 
      samples. Five chlorinated phenols including 3-chlorophenol (3CP), 4-chlorophenol 
      (4CP) 2,4-dichlorophenol (DCP), 2,4,6-trichlorophenol (TCP), and 
      pentachlorophenol (PCP) were separated by CE with Tris/sodium dihydrogen 
      phosphate solution containing methanol 1% (v/v) as the run buffer. CFLME related 
      parameters were investigated and optimal enrichment was obtained by using 0.3 mol 
      L(-1) Tris as acceptor and with a sample pH 5.0, a sample flow rate of 4.0 mL 
      min(-1), and an enrichment sample volume of 150 mL. The detection limit (S/N= 3) 
      was 6.9, 1.0, and 1.7 ng mL(-1) for DCP, PCP, and TCP, respectively. The 
      reproducibility (RSD%, n = 6) was 5.7 for DCP, 2.5 for PCP, and 2.8% for TCP (n = 
      6). The proposed method was applied to the determination of chlorinated phenols 
      in spiked water samples with relatively satisfactory recoveries.
