摘要： The voltammetric responses of diethylstilbestrol (DES) and malachite green (MG) were investigated at the conductive carbon black paste electrode (CCBPE), which exhibited an attractive electroanalytical ability. The mechanisms of the electrode reactions were studied. And the experimental parameters influencing the voltammetric responses of the two species, including supporting electrolyte, pH, accumulation time and potential, etc., were optimized. Based on the results, a simple and rapid method for detecting DES and MG simultaneously was established. Under optimal conditions, linear voltammetric responses of DES and MG were obtained in the range of 16-465 nM and 10-510 nM, respectively. For DES and MG the limit detections were 8 nM and 6 nM (s/n=3), respectively. The concentrations of DES and MG in real fishery water samples were tested successfully, indicating that the new method was strongly promising in the environmental monitoring application.
