摘　　要：利用二氧化锡修饰铂丝柱电极,以其为电化学传感器对水体中化学耗氧量进行检测,探讨了最佳检测电位和有机化合物在该电极上的电化学行为,并对实际水样的COD进行了检测。实验结果表明,该电极对有机化合物有明显的电催化活性,用其测定水体中COD具有很好的效果。In this paper, the SnO2 modified Pt - thread pillar electrode was prepared and was employed as an electrochemical detector to determine the COD in waste water. The detecting potential was optimized and the electrochemical behavior of organic compounds at the modified electrode was studied. The modified electrode showed good electrocatalytic activity to organic compounds, and the effect of determine COD with it is good.
