【摘要】 对铜－聚四氟乙烯复合电极的制作方法进行了研究，对其电分析性能做了考察，用ＸＰＳ及ＳＥＭ对电极表面形态进行了表征．实验证明，以５ｍＡ／ｃｍ２的电流密度镀０．５Ｃ所得的复合电极有优良的机械性能和分析性能，将其与裸铜电极相比，前者不仅加宽了电位窗，而且增大了对醇醛糖的恒电位安培法响应．将它做成流动注射分析检测池的柱状工作电极，则背景信号降低，使检出限进一步降低．可检出３×１０￣（－６）ｍｏｌ／Ｌ葡萄糖．本文还对它们的电氧化过程作了探讨．更多还原

【Abstract】 In this paper,the procedure of preparation of Cu-PTFE composite electrode by electroplating was investigated and the electroanalytical properties of alcohol, aldhyde and carbohydrate on Cu-PTFE composite electrode were examined.The results from experiments indicated that the detection limit by constant potential amperometry with Cu-PTFE composite electrode in flow injection analysis was lower（3×10￣（-6） mol/L for glucose） and the process of electrode was electrocatalytic oxidation by Cu₂O₃.更多还原
