AB  - Hot electron-induced cathodic electrochemiluminescence of the 
      Ru(bpy)(3)(2+)/S(2)O(8)(2-) system was investigated at an oil film-covered carbon 
      paste electrode (CPE) under cathodic pulse polarization for the first time. 
      Compared with other electrodes, the CPE is of lower background, better stability 
      and reproducibility. The method is also applied to the determination of catechol. 
      Under the optimum conditions, the linear correlation between the quenched ECL 
      intensity (DeltaI) and the logarithm of catechol concentration (logC(catechol)) was 
      observed over the range of 2.0x10(-10) mol/L-4.0x10(-9) mol/L and 4.0x10(-9) 
      mol/L-4.0x10(-7) mol/L with the limit of detection (LOD) of 2.0x10(-10) mol/L, 
      which is lower than the other reported methods. The proposed method is applied to 
      determine catechol in reservoir water. The mean recoveries of 83.3%-99.0% and the 
      relative standard deviations (RSDs) of 0.8%-2.2% were obtained.
