摘要: 用电沉积法在碳糊电极表面修饰铜制得修饰碳糊电极，研究了葡萄糖在铜修饰碳糊电极上的电化学行为，用计时安培法对葡萄糖进行了测定，在浓度为1.01 × 10−7~1.20 × 10−5 mol/L范围内葡萄糖浓度与电流呈线性关系，检出限为5.0 × 10−8 mol/L。并且将该方法用于实际样品的检测，结果表明该方法选择性好，分析速度快，操作简单。
Abstract: A copper modified carbon paste electrode was prepared by electrodeposition and the electro-chemical behavior of glucose at the modified electrode was investigated. The determination of glu-cose was achieved by chronoamperometry, revealing that the concentration of glucose changed linearly with the current when the concentration ranged from 1.01 × 10−7 to 1.20 × 10−5 mol/L, and the detection limit was 5.0 × 10−8 mol/L. The methodology was applied in detection of actual sam-ples, manifesting several features including high selectivity, quick analysis and easy operation.
