AB  - In the present work, the micellar electrophoretic separation of five 
      chlorophenols (CPs) on a functionalized poly(dimethylsiloxane) (PDMS) microchip 
      with amperometric detection was performed. In order to achieve high resolution by 
      controlling the electroosmotic flow (EOF) as well as signal detection by 
      suppressing analytes adsorption, the microchannel was functionalized by 
      poly(diallyldimethylammonium chloride) (PDDA)/SiO2 nanospheres (NSs)/ 
      poly(sodium-p-styrenesulfonate) (PSS), via an approach of layer-by-layer 
      assembly. Five chlorophenols (2-chlorophenol, 4-chlorophenol, 2,4-dichlorophenol, 
      2,3-dichlorophenol and 2,4,6-trichlorophenol) were efficiently separated in this 
      microchannel (3.7 cm of length) within 120 s. A resolution of at least 2.4 was 
      obtained with a 10 mM phosphate buffer solution (PBS) (pH 9.48) containing 20 mM 
      sodium dodecyl sulfate (SDS) and 50% (v/v) acetonitrile as a carrier under 
      optimized conditions. A graphene-modified carbon microdisk electrode was used for 
      high-sensitivity detection. Its characteristics were investigated by cyclic 
      voltammetry (CV) and electrochemical impedance spectroscopy (EIS). For those CPs, 
      linear ranges of 0.08-5, 0.06-5, 0.04-5, 0.04-5 and 0.30-20 muM and detection 
      limits of 0.021, 0.026, 0.022, 0.019 and 0.054 muM were obtained, respectively. 
      The method was successfully applied for the analysis of some wastewater samples 
      with satisfactory recovery.
