AB  - A sensitive method of CZE-ultraviolet (UV) detection based on the on-line 
      preconcentration strategy of field-amplified sample injection (FASI) was 
      developed for the simultaneous determination of five kinds of chlorophenols (CPs) 
      namely 4-chlorophenol (4-CP), 2-chlorophenol (2-CP), 2,4-dichlorophenol 
      (2,4-DCP), 2,4,6-trichlorophenol (2,4,6-TCP), and 2,6-dichlorophenol (2,6-DCP) in 
      water samples. Several parameters affecting CZE and FASI conditions were 
      systematically investigated. Under the optimal conditions, sensitivity 
      enhancement factors for 4-CP, 2-CP, 2,4-DCP, 2,4,6-TCP, and 2,6-DCP were 9, 27, 
      35, 43, and 43 folds, respectively, compared with the direct CZE, and the 
      baseline separation was achieved within 5 min. Then, the developed FASI-CZE-UV 
      method was applied to tap and lake water samples for the five CPs determination. 
      The LODs (S/N = 3) were 0.0018-0.019 microg/mL and 0.0089-0.029 microg/mL in tap water 
      and lake water, respectively. The values of LOQs in tap water 
      (0.006-0.0074 microg/mL) were much lower than the maximum permissible concentrations 
      of 2,4,6-TCP, 2,4-DCP, and 2-CP in drinking water stipulated by World Health 
      Organization (WHO) namely 0.3, 0.04, and 0.01 microg/mL, respectively, and thereby 
      the method was suitable to detect the CPs according to WHO guidelines. 
      Furthermore, the method attained high recoveries in the range of 83.0-119.0% at 
      three spiking levels of five CPs in the two types of water samples, with relative 
      standard deviations of 0.37-8.58%. The developed method was proved to be a 
      simple, sensitive, highly automated, and efficient alternative to CPs 
      determination in real water samples.
