摘　　要：研制了二乙基二硫代氨基甲酸铜电位型传感器 ,并考察了电极性能 ,该修饰电极对 Cu2 +具有类能斯特响应。A potentiometric sensor was fabricated by adding copper diethyldithiocarbamate directly into carbon paste. The property of the sensor was described. The sensor gave a linear response of the potential with respect to copper(Ⅱ) concentration in the range of 3.0×10 -6 ～5.0×10 -2 mol/L,with a slope of 25～30 mV/ p C,and detection limit of 1.0×10 -6 mol/L. The sensor was applied to determination of copper(Ⅱ) in samples.
