AB  - Gold nanoparticles (AuNPs) of different sizes were synthesized by the citrate 
      reduction method. It was found that AuNPs could enhance the chemiluminescence 
      (CL) of the luminal-NaOH system and 2,4-dichlorophenol (2,4-DCP) could inhibit 
      AuNPs-luminal-NaOH CL signals in alkaline solution. CL spectra, UV-visible 
      spectra, and transmission electron microscopy (TEM) were used to investigate the 
      CL mechanism. On the basis of the inhibition, a flow-injection CL method has been 
      established for determination of 2,4-DCP in water samples. Under the optimized 
      conditions, the linear range for determination of the 2,4-DCP was 0.1 x 10(-6) to 
      20 x 10(-6) g mL(-1), LOD (limit of detection, S/N = 3) was 1.36 x 10(-8) g 
      mL(-1), with RSD of 1.8% (n = 11). This method has been successfully used for 
      analysis of 2,4-DCP in environmental water samples.
