AB  - Gentian violet (GV) was found to quench the electrochemiluminescence (ECL) of the 
      tris(2,2'-bipyridyl)ruthenium(II)/tris-n-propylamine (Ru(bpy)3(2+)-TPA) system at 
      a glass carbon electrode (GCE). Based on the ECL signal changes, a simple and 
      ultrasensitive detection method for GV in aquatic water was established. Under 
      the optimized conditions, the quenched ECL intensity versus the logarithm of the 
      concentration of GV was linear over a concentration range from 1.0x10(-10) to 
      5.0x10(-7) mol L(-1), and the limit of detection (LOD) was found to be 
      4.5x10(-12) mol L(-1) (S/N=3). The results obtained by the ECL system were better 
      than other reported methods in literatures in terms of sensitivity or linear 
      response range. The method was successfully applied to determine GV in aquatic 
      water, and the relative standard deviations (RSDs) were found less than 6.3%, and 
      the recoveries were obtained from 98.7 to 111.0%. Moreover, a possible mechanism 
      of the quenching effect was primarily discussed based on UV-visible absorption 
      spectra, cyclic voltammograms and IECL-E curves.
