A novel electrogenerated chemiluminescence (ECL) method for the determination of pyrocatechol has been developed in this paper based on the quenching effect of pyrocatechol on the cathodic ECL intensity of the Ru(bpy)₃²⁺-CdTe quantum dots (QDs) system in phosphate buffer solution (pH=7.0). The effects of buffer concentration, pH, CdTe QDs concentration, Ru(bpy)₃²⁺ concentration, scan rate and potential windows on the luminescence of the system were investigated. Under the optimal experimental conditions, the log value of ECL intensity and the log value of pyrocatechol concentration showed a good linear relationship in the range of 7.0×10^-8~4.0×10^-5mol/L with the detection limit of 2.3×10^-8mol/L (3σ). The relative standard deviations (RSD) of the ECL intensity for 4.0×10^-6mol/L standard pyrocatechol solution was 1.1% (n=6). The present method has been successfully used to determine pyrocatechol in simulated environmental water samples with average recoveries from 95.0% to 105.7%.
